Startling Stories March 1939 – Mutant Man Grapples Robotic Sphere

A lurid crimson robot head dominates the composition, its single cyclopean eye and grated mouth grinning with mechanical menace as a bare-chested, wild-haired figure — skin rendered in sickly ochre tones — wrestles it with both hands. Radiating yellow light beams burst from behind the sphere like a mechanical sunrise. A vignette panel at right shows human figures in apparent peril, adding narrative depth. The cover brims with tactile energy: coiled machinery, gleaming metal, and flesh in dramatic contrast.
