Richie Rich & Casper #18

Harvey's cheerful duo is diving headfirst into treasure in this June 1977 team-up, as the cover shows Richie Rich and Casper the Friendly Ghost tumbling through a cave overflowing with gold coins, money bags, gems, and loose bills — with a mysterious Ali Baba figure looking on and a speech bubble declaring "Open Sezme!" The cover banner promises that Richie and Casper meet Ali Baba and the 40 Thieves inside, setting up a storybook adventure with a distinctly rich twist. At just 30 cents, this Harvey World title delivers the warm, playful charm that made these two an endearing pairing throughout the decade.
