Somewhere between MythologyGag, DevelopmentGag, ContinuityNod and ProductionThrowback. This is when a work references stylistic changes since prior works in the same series.

When this is used to refer to events that happened at the time of the referenced style, it's a RetrauxFlashback.

* ''{{Garfield}}'' marked its 25th anniversary with a StoryArc where 2003 Garfield meets 1978 Garfield.
* [[http://www.gocomics.com/luann/2010/03/14 This]] {{Luann}} strip that ran several days before its 25th anniversary has the 2010 main characters commenting on their 1985 designs. "I'm glad WE [[{{Irony}} never looked that dumb...]]"
* In one "Ginger Meggs" strip, Ginger has a caricature done and says it looks nothing like him. The caricature is the original, when-your-grandparents-were-young artwork.
* There was an {{Alley Oop}} story arc a few years ago where Alley's no-good cousin Early Oop shows up in Moo and makes trouble by impersonating Alley, despite Alley's insistence that they look nothing alike. Early is designed to look like Alley's original appearance.

[[folder:Video Games]]
* At one point in the original ''VideoGame/PaperMario'', there's a pot Mario can jump into. If he does, he comes back out as his sprite from ''VideoGame/DonkeyKong''.
** There's a similar curtain that does this in ''VideoGame/SuperMarioRPG''.
** In ''PaperMarioTheThousandYearDoor'', There's a curtain in an area near the end of the game that does this to Mario ''and'' all of his partners.
** Mario's blue-clothes-red-overalls PaletteSwap in the ''SuperSmashBros.'' games is the color scheme he used in his first VideoGame appearance as the protagonist in ''VideoGame/DonkeyKong'' which was also famously featured on the cover of the first issue of ''Nintendo Power''.
* The Timeless River in ''VideoGame/KingdomHeartsII'' is one big one to black and white {{Disney}} shorts. Also in the same game, at the start as well as in the Timeless River Sora wears his outfit from the original game.
* The "1st gen ring" from ''VideoGame/TheLegendOfZeldaOracleGames''.
* ''VideoGame/MetalGearSolid4'' is full of these, starting with flashbacks to the {{Playstation}}-era graphics of ''VideoGame/MetalGearSolid'', up to and including [[spoiler:a fully playable flashback sequence with graphics and gameplay straight out of ''VideoGame/MetalGearSolid'']].

[[folder: Web Animation]]
* This occurs in the WebAnimation/HomestarRunner cartoon [[http://www.homestarrunner.com/deck.html No Hands On Deck!]]
-->'''Homestar Runner''': Yeah, melonade! We haven't talked about that much lately! Maybe we can eat some (His head turns into his 2000 design's head)\\
'''2000 Homestar''': marshmallows (His head turns back to normal)\\
'''Homestar Runner''': too!\\

[[folder:Webcomics]]
* A LeaningOnTheFourthWall version appears in Webcomic/GirlGenius - the flashbacks are all presented in sepia tones, making them appear to be old print comics that have faded and browned. Surprisingly effective at conveying the point though.

[[folder: Western Animation]]
* In the ''WesternAnimation/TheSimpsons'' episode "Homerazzi" there is one scene where Marge is taking a picture of Homer, Bart, and Lisa as they appeared on "The Tracy Ullman Show" under a banner saying "Happy 1987". After the picture is taken, they fix their hair to become the normal versions.
* In ''WesternAnimation/RunawayBrain'', after the mind swap Julius finds some photos in Mickey's wallet. One of them is of Mickey as he looked in ''WesternAnimation/SteamboatWillie''.
