Ape-Men of Xlotli — Astounding Stories of Super-Science Clayton Pulp Cover

A snarling, dark-furred ape-creature lunges from the shadows, its fanged maw open wide as a muscular human hero grapples it in brutal close-quarters combat — while a terrified woman recoils to the right. The composition is raw and claustrophobic, packed with writhing figures that fill every inch of the frame. The monochromatic reproduction deepens the menace of this subterranean nether-world encounter, evoking the damp stone and darkness of an underground realm teeming with savage half-human beasts.
