Sheldon Moldoff was one of Bob Kane's anonymous cartoonists. Comic-readers would buy Batman comic-books thinking that they were Bob Kane's, when they were really Sheldon Moldoff's. Sheldon Moldoff helped to co-create Calendar Man, Poison Ivy, Clayface (Matt Hagen) and many other characters. Besides making Batman comic-books, he drew the covers for the Green Lantern in All-American Comics #6 and the Flash in Flash Comics #1. Sheldon Moldoff has pencilled 146 issues of Detective Comics, 121 issues of Batman, and 61 issues of World's Finest Comics.
