The Talking Gorilla
The often told story is that someone at DC Comics noticed that they sold more copies every time a cover of theirs featured a gorilla.
I think this is a subject for psychologists to figure out, but apparently a lot of comic book readers are hot for gorillas. Well, gorilla-lovers, try to control yourselves because I have a talking gorilla story for you. It's from Fawcett's Whiz Comics #103, 1949.
The artwork is uncredited, but looks like a very young Kurt Schaffenberger did it, or at least had a hand in it. Lo-Kar the gorilla knows, but at least for now he ain't talkin'...
