Science Fiction Quarterly #4 — Tarrano the Conqueror, Ray Cummings 1941

Figures clad in vivid red uniforms hurtle through a turbulent sky above a gleaming futuristic cityscape, locked in desperate aerial combat around a massive rotating mechanical device — its churning gears threatening to pull them into oblivion. A blonde woman in red reaches out from the machine's rim while armored figures on winged sleds swoop and dive overhead. This kinetic, vertigo-inducing cover illustration captures the breathless action of Ray Cummings' full-length novel 'Tarrano the Conqueror.'
