Hot Stuff, the Little Devil #61

Harvey's pint-sized red devil is putting on quite a show on this 1964 cover — dressed in a jaunty top hat and cracking a ringmaster's whip, Hot Stuff coaxes a wide-eyed tabby cat through a blazing ring of fire. It's a charming, circus-flavored image that captures the little devil's mischievous warmth perfectly, and at 12 cents it was an easy pick for young readers in 1964.
