What a Cartoon! (later known as The What a Cartoon! Show and The Cartoon Cartoon Show) is an American animated anthology series created by Fred Seibert for Cartoon Network. The shorts were produced by Hanna-Barbera Productions; by the end of the run, a Cartoon Network Studios production tag was added to some shorts to signal they were original to the network. The project consisted of 48 short cartoons, intended to return creative power to animators and artists, by recreating the atmospheres that spawned the iconic cartoon characters of the mid-20th century. Each of the shorts mirrored the structure of a theatrical cartoon, with each film being based on an original storyboard drawn and written by its artist or creator.
