Amazing Stories June 1958 — 'The Thing From Underneath' Alien Hand Cover

A bold red background charged with danger frames this tense confrontation in crimson, gold, and sickly green. A uniformed security guard, revolver drawn, peers through a circular vault-like hatch as a grotesque green alien claw reaches through the gap — unseen, unknowable, threatening. The checkerboard floor grounds the scene in pulpy domesticity before the cosmic horror of that reaching hand shatters it. The composition masterfully compresses threat and authority into a single claustrophobic moment of science fiction dread.
