I don’t know why Sheldon Mayer drew the entire issue of Funny Stuff #5 (1945). In other issues each feature was drawn by a different artist. Mayer, who had been the editor, had quit that position in order to write and draw. Maybe this was a special project for him. Whatever the reason, he blended his special kind of cartooning magic into what was already a really good title for publisher M.C. Gaines.
Gaines had split off for a time from his partners, the publishers of DC Comics, and his books were All American Comics. Before the war ended he sold his entire line, along with his paper ration, to DC. It included characters like Green Lantern, the Flash, and Wonder Woman, all of which at one time or another Mayer edited.
