The Great Gazoo #15

From Charlton Comics in 1976, this Hanna-Barbera tie-in finds the tiny green alien the Great Gazoo and Fred Flintstone sharing a flying saucer cockpit somewhere in the cosmos — complete with a space traffic light showing "STOP" and "GO" and a flock of large birds soaring below them. It's a cheerfully absurd snapshot of Stone Age meets outer space, exactly the kind of warm, funny energy that made this series a treat for young readers.
