Sunday is Monkey Covers day here at YACB. Because there's nothing better than a comic with a monkey on the cover.
What do you need to make the perfect comic cover from 1940? A mad scientist, a damsel in distress, a gun-wielding manly hero, and a monkey-beast-thing. It's all on George Tuska's cover to Weird Comics #1!
(Standard disclaimer about monkey-beast-thing probably not really being monkeys applies.)
