Superduperman! was a Mad parody of the Superman comic book. It was drawn by Harvey Kurtzman for Mad #4, April-May 1953. This was the first issue of the comic book that actually sold well. (Gaines let Kurtzman turn Mad into a magazine in 1955 as an incentive for him to stay with EC. Mad was the most profitable title at that time, because the horror and suspense comics that used to be the most profitable were not allowed under the Comics Code Authority.)
