Amazing Stories June 1927 – Eyeball Creatures Attack, Frank R. Paul Cover

More frenetic than Paul's comparatively stately planetary vistas for early Amazing Stories, this June 1927 cover erupts with swirling bioluminescent eyeball creatures attacking a white-coated scientist brandishing a pistol, while a red-skinned alien and a glowing ethereal woman loom behind a crowd of goggle-eyed green aliens. The lurid purple sky, coiling tentacular eye-monsters, and desperate human defender encapsulate Hugo Gernsback's editorial mission to make scientifiction viscerally thrilling on the newsstand.
