Fantastic Adventures 'King of the Dinosaurs' Cover, October 1950

Two savage warriors do battle atop a thrashing, wounded dinosaur in a primal jungle swamp. One spear-wielding figure rides the beast's back while a second combatant grapples from the side, both silhouetted against a blazing yellow-green sky. The creature's reptilian hide is rendered in cool blue-grey, streaked with blood-red wounds, creating visceral contrast against the lurid tropical palette. Classic lost-world pulp fantasy at its most gloriously overheated.
