Richie Rich & Casper #24

Two of Harvey Comics' most beloved characters share the spotlight in this July 1978 team-up, as a wide-eyed Richie Rich clutches a dollar bill while currency swirls all around him in a dazzling geometric vortex — and a startled Casper the Friendly Ghost floats right in the middle of it all. A cover blurb warns that "the sorcerer has turned the money purple," teasing the wonderfully strange premise of the interior story, "The Eye of an Artist." It's a charming snapshot of late-'70s Harvey Comics at its most imaginatively silly, promising twice the fun for 35 cents.
