The Great Gazoo #16

Charlton's long-running Flintstones spin-off puts the little green alien front and center in this 1976 issue, where the cover shows Gazoo cheerfully hovering on a cloud above what appears to be a bubbling volcanic cauldron — complete with a frying pan of eggs sizzling atop it in truly prehistoric style. It's a charmingly absurd snapshot that sets the tone perfectly for the interior story, "The Goodwill Ambassador." At just 30 cents, this Hanna-Barbera production delivers the kind of lighthearted, imaginative fun that made Gazoo such a delightful addition to the Stone Age universe.
