Lance: Hey Captain, what's that?A Calling Card is a piece of evidence or item deliberately left at the scene of a crime to serve as perpetrator's "signature". Sometimes it's a literal playing card or gamepiece left near the scene of the crime, or perhaps the victims are arranged in strange poses. Actual calling cards are rare in Real Life, because it would make it very easy for the cops to track you down; but in fiction, it seems like every villain has to have one for stamping their achievements with. Occasionally, a Genre Savvy character may even use another villain's calling card to frame them. If the villain is well known, and their calling card shows up before they're introduced in the current continuity, (or if said Villain has been missing or dead for some time), then it's a nice Sequel Hook, or simply a hint of what's to come. Sometimes, the calling card may be a result of the villain's M.O. or distinctive Weapon of Choice. One obvious example: vampires always leave their characteristic two-holed neck bite. See also Criminal Mind Games, Idiosyncrazy, Poetic Serial Killer. This has become a Dead Horse Trope in Comic Books, where it was once a staple. A hero may also have a Calling Card, especially one who typically disappears after stopping the criminals rather than hanging around to discuss things with the police. For actual calling cards (which a criminal may also leave, although it's a bit obvious), see My Card.

Anime and Manga
- In Dragon Ball when Tambourine is sent by his father Piccolo Daimao to murder martial artists to prevent them from sealing him away, at the site of each murder he would leave a piece of paper with the Japanese symbol for demon near the body.
- Phantom Thief X from Majin Tantei Nougami Neuro, who leaves a "red box" at the crime scenes (actually a clear glass box filled with the liquefied remains of his victims).
- The titular character from Mouse leaves his card, before the theft like several other Phantom Thieves.
- The Death Note allows its user to not only kill remotely but also control victims' behavior shortly before they die. Light Yagami uses this ability to send a taunting message to L.
- Speaking of Holden Caulfield, in Ghost in the Shell: Stand Alone Complex, The Laughing Man had a smiley-face surrounded and a quote from Catcher in the Rye. As it turns out, all the crimes that were marked just by the smiley-face were performed by copycats, but following the J.D. Salinger quote eventually led Section 9 to the real Laughing Man.
- In one early episode of Sonic X, Rouge the Bat steals a very large diamond... and replaces it with a card with a stylized picture of her on it, along with the words "thank you".
- The titular thief of Lupin III often inverts this by sending calling cards before he pulls off his heists. It seems rather foolish, but often his targets' attempts to increase or alter their security end up playing right into one of his Batman Gambits and allow him to accomplish the theft. Also a reference to Arsène Lupin, his grandfather.
- Lupin uses two calling cards in Lupin III: Dead or Alive. One is in the form of a video where he is a Parody Name of 21st Century Fox, announcing that he would steal the treasure of Drifting Island. In the other, he uses an advertising balloon to announce his theft of Headhunter's Daughter.
- In Lupin III Island Of Assassins, Tarantula forges one of Lupin's to get him involved in their plans.
- This was also done by Kaitou in Magic Kaito and Detective Conan
- Cat's Eye has two different calling cards. The titular girls leave a business card with a stylized cat and the words "Cat's Eye" on it, while the thief Masato Kamiya (nicknamed "The Rat" by the police) leaves a coin mounted on a pendant. Like many Gentleman Thief characters, the girls sometimes send calling cards before the heists: the police squad assigned to capture them has two members with the bad habit of confiding to them their strategies to capture Cat's Eye (and, in one memorable occasion, discussed the strategy in their coffee house), and live near their police station enough to use binoculars and lip-read the rare plans the officers won't discuss with the girls.
- While Kamiya does it for fun, the girls have a good reason for it: their assumed name as Cat's Eye and them stealing only Michael Heintz's paintings are part of a complicated and desperate attempt to contact their father, Heintz himself, or at least find out if he's still alive, without tipping off the men who tried to kill him and stole his paintings in the first place.
- Eroica in From Eroica with Love leaves a card with the series title on it.
- From The Golden Age of Comic Books through The Bronze Age of Comic Books, most of Batman's Rogues Gallery left Calling Cards, either explicitly (The Joker's playing cards and the Riddler's conundrums), or in the form of Signature Crimes: Two-Face's crime sprees always revolved around the number two, for instance. This was often Lampshaded; even in The Golden Age of Comic Books, the Riddler's compulsion was flat-out stated to be his downfall. In the current comics, however, it's a Dead Horse Trope.
- The serial killer from The Long Halloween would kill on a holiday and leave behind some knickknack related to the date—the press dubs them The Holiday Killer. And in the sequel Dark Victory, the next serial killer leaves behind incomplete Hangman games.
- The Joker is famous also for victims with a hideous grin on their faces due to Joker Venom (or in one case, carved Glasgow smiles).
- Hero example: Batman himself sometimes leaves a card with a bat-symbol next to unconscious thugs.
- In Watchmen, Rorschach's calling card is a piece of paper with a mirrored lowercase letter R written on it.
- In Spider-Man early in Carnage's killing sprees he would write "Carnage Rules!" in his victim's blood near the body.
- Spider-Man himself would occasionally leave a note to the police tacked onto a felon he had left webbed and hanging from a streetlamp, signed, "Courtesy of your Friendly Neighborhood Spider-Man".
- Lobster Johnson, of Hellboy fame, would burn his symbol, a stylised lobster claw, into his victims' foreheads using the palm of his hand. He also had actual calling cards that he would leave for the police.
- In V for Vendetta, V is fond of graffiting walls with a stylised V, which is meant to look similar to the symbol for anarchy.
- Captain America: The Red Skull used to have two calling cards: his Red Dust, a poison that made the victim's face turn red and skull-like, and a leitmotif of Chopin's "Death March" which he would arrange to have played when he struck, sometimes in very clever ways. He hasn't used either of these in years, having gone to more subtle evil schemes.
- The Phantom has two calling cards, both in the form of rings. He wears a ring with a skull emblem on his right hand, which leaves a permanent skull-imprint on the faces of his enemies when he punches them hard enough, forever branding them as the Phantom's enemies. On his left hand, he wears a ring with a symbol of four 'P's in a circle. By pressing the dye-emitting ring into the hand of an ally, he leaves the four-P emblem as a permanent mark on their skin, a sign to the world that they are protected by the Phantom.
- Parenthetically, the Phantom's skull ring was the subject of a Mythbusters episode, as the Build Team attempted to determine if a strong enough punch could leave a permanent indentation in someone's skull. For the record, it was busted; any punch hard enough to leave such a mark would also crack said skull like an egg. Perhaps the skull ring also had permanent dye like the four-P ring, and the Phantom just punched his enemy because he deserved to be punched. (Mythbusters also didn't consider making the edges of the ring sharper and seeing what happened.)
- One of the many serial killers in Judge Dredd was nicknamed Lefty due to his habit of always leaving his victims' left hands near the scene of the crime. Turns out there was a grisly justification for this: he was attempting to set a record for the number of people killed in a single night, and leaving behind the left hands ensured that all the kills would be credited to him.
- The Clock, from Centaur Publications and later Quality, leaves as his calling card an image of a clock-face over a domino mask along with a message.
- Mister Midnite, from Silver Streak Comics, leaves a watch dial with the hands set at midnight as his calling card.
- Black Diamond, from Black Diamond Western, has a playing card with the suit of diamond as his calling card.
- Mickey Mouse: The Phantom Blot's calling card is an ink blot. He'll usually leave a message with it, but sometimes not — one time Mickey finds himself framed by the Blot, and then notices there is an actual ink blot on his jacket.
- The Golden Age Sandman and Vigilante, both from DC Comics, left poems.
There is no land beyond the lawWhere tyrants rule with unshakable power!'Tis but a dream from which the evil wakeTo face their fate, their terrifying hour!"
Some play games for sky-high stakes,And some play penny-ante.But those that gamble with the law,Must pay the Vigilante!

- It was Marv who did this; Harry thought it was stupid and berated him for it. Near the end of the movie when they both get caught, the arresting officer mentions that they know which houses they robbed due to the running sinks.
- In the first Austin Powers, the Irish killer has his little charm bracelet from which he leaves little trinkets at the scene of each crime. Cue joke: Scotland Yard is "always tryin' to get me Lucky Charms!"

- The Executioner. Elite sniper turned vigilante Mack Bolan leaves a miltary marksman's medal at the scene of his killings. Sometimes he has one delivered to a future target as psychological warfare. His enemies have been known to leave such medals at murder scenes, either to frame Bolan or cover up for their own internal disputes (one Mafia capo who cut the throat of a rival might have gotten away with it, if Bolan hadn't chosen that moment to attack in a completely different area). The latter tactic was used so often that one underling reporting a Bolan hit got beaten up "for pulling that stunt", until Bolan (who'd let him live so he could follow the man to his superiors) walked through the door and started shooting.

- Technically, the fact Thieves and Assassins always leave a receipt could be considered a calling card. This is how you know you were visited by a licenced professional, and not a common criminal.
- The suspense novel The Caper of the Golden Bulls is about a retired thief coerced into a new caper; he laments that he can't get the aid of another master thief known as the "Ace of Diamonds." The Ace had a bizarrely elaborate signature: the ace of diamonds playing card, with a gryphon's head drawn on it, and then a stiletto driven through the card. It's eventually revealed that the gryphon's head referred to the thief being a lovely young woman named Grace — "gr" from "gryphon" plus "ace" — so she was telling the authorities her name every time she pulled a theft. And she turned out to be the hero's girlfriend, so the Ace of Diamonds was available to help.

However, upon raiding the balloon killer's house and shooting him in a fierce firefight, the balloon killer implies that he was not responsible for the boy's disappearance this time around, which was shortly thereafter confirmed by Patrick Jane via both a phone call and a note in one of his partner's pocket that he somehow planted in there.

- Subverted in the Turkish crime-drama Yılan Hikayesi. Investigating an elusive crime boss called "The King", the protagonists occasionally find a single rose flower was left in the places that the King was believed to have been. The subversion comes from the fact that they were not meant for the cops. They were meant as a message for his ex-wife whom he could not meet face-to-face for fear of retaliation by his enemies but still loved dearly. The locations where the roses were found were the places his ex-wife had gone as part of her own investigation on her husband's disappearance.

- Episode 2.01 of White Collar featured a bank robber who left actual calling cards at his crime scenes.

- In the short-lived NBC series, Sword Of Justice, protagonist Jack Cole would use playing cards, the three of clubs, diamonds, hearts, and spades as his calling cards. The three of clubs was left with the target of each episode, as a warning that he was going down. The three of diamonds would be used to pass information to the police.

- The X-Files:
- When a still-burning Morley cigarette is left on the ground or in an office ashtray, that's a sign that the Cigarette-Smoking Man has been there recently. Since he's The Chessmaster who's anything but careless, it's very likely these are left deliberately.
- In the episode "The End", a guard in the prison where the Conspiracy's failed hired assassin is held (pending questioning) hands the prisoner a threatening note ("You're a dead man") written on the cut-out side of a Morley cigarette carton—indicating that it was a message from the Cigarette-Smoking Man. A second time, the prisoner receives another cut-out carton side, which has nothing written on it, right before the guard shoots him.

- According to the artbook of Lisa, Geese Thompson, one of the recruitable characters was a serial killer who left rhymes about his identity near his crime scenes.
