Richie Rich & Casper #45

Harvey's beloved team-up title brings Richie Rich and Casper together in this September 1982 issue, where the cover — penciled by Warren Kremer — sets up some mischievous mayhem: a wild, gremlin-like creature identified as Dr. Frankenspook brandishes a sparking ray device while declaring "YOU next, Casper!", sending the worried little ghost and a wide-eyed Richie scrambling. The cover tagline promises that Dr. Frankenspook's "Switcherooray" turns a person silly, which looks entirely believable given the chaos already unfolding. It's a cheerful, energetic setup that makes this team-up book hard to pass up.
