Five-Score Comic Monthly #69

In "The Great Superboy Hoax! Part 1," sports promoter Colin stumbles into an outlandish scheme when he attempts to train interdimensional animals for a spectacle—only to discover they devour metal and grow increasingly uncontrollable. Written by Jack Miller and illustrated by Howard Purcell, this 1964 adventure blends sci-fi whimsy with escalating chaos, all rendered with the crisp detail of Curt Swan’s cover and George Klein’s inks.
