Art Evolution: The studio went through a fair amount of it. Their earliest work had a very rubbery, bizarre feel to it; Lantz began working with a hyper-cute style in about 1933, while the studio's other director, Bill Nolan kept with the original approach until his firing at the end of the following year, cementing Lantz's cutesy style as the one used by the studio. This lasted until 1938, when Lantz allowed a number of animators the chance of directing, leading the studio's cartoons in 1938-39 having a range of different styles. By the end of 1939 things had settled down to having Alex Lovy as the main director, and their cartoons became amateurishly drawn, misguided attempts at imitating the West-Coast animation style pioneered by Disney and Looney Tunes shorts, and suffered from mushy animation. Shamus Culhane tried to beef up the studios art quality with Disney-esque articulation, with varying degrees of success, but this was impeded by indifference from most of the artists, as well as sloppy inking and inbetween work. Dick Lundy managed to bring genuine, albeit budget constrained, Disney-quality animation to the studio during his tenure. From the 50's and onward, Lantz switched to a more conservative, stiffer art style for the rest of the studios life.
Benevolent Boss: Walter was considered by his employees to be one of the best employers to work for during the Golden Age.
Bowdlerize: When Lantz brought his cartoons to TV, a lot of them went through heavy editing to appease the censors—and some, like "Abou Ben Boogie" and "Scrub Me Mama with a Boogie Beat" were banned outright.
Long Runner: Lantz's studio was the longest surviving theatrical cartoon studio, thanks in part to Lantz being accustomed to working with low budget cartoons, and thus having no problem adjusting to the rise of the Dark Age. However, the studio finally gave up the ghost in 1972, as theatrical cartoons had become completely unprofitable by that point.
Missing Episode: Universal claims that some of the negatives to the studios early 30's output have been lost.
Ms. Fanservice: Some of his shorts demonstrated this, such as "Scrub Me Mama With a Boogie Beat", "Abou Ben Boogie" and "The Greatest Man in Siam".
Off Model: The early Lantz shorts were prone to shameless animation goofs.
Public Domain Animation: A handful of his shorts have slipped into the Public Domain, most notably the Woody Woodpecker short "Pantry Panic", as well as "Scrub Me Mama With A Boogie Beat".
Rotoscoping: Blatantly used at several points in "Just a Jitterbug".
Stealth Pun: Later title cards in his cartoons featured Woody riding a horse, while carrying a large lance poking through the words "A Walter Lantz Production".
Wartime Cartoon: Lantz did several of these, most notably "The Enemy Bacteria", as well as a Warner Bros. "Seaman Hook" short that was outsourced to his studio, the short being "Take Heed, Mr. Tojo". Even his mainstream theatrical shorts had some nods to the war going on, most notably "Ration Bored".
