Giant Cyclops Sea Monster Attacks Native Canoe — Fantastic Adventures June 1948

A colossal aquatic creature of impossible biology — a single massive eyeball embedded in a writhing, barnacled body — erupts from churning waters in a catastrophic display of prehistoric monster science. Native American figures scramble from an overturned canoe as the beast hurls victims skyward. The creature's tentacular, fleshy bulk dominates the composition, its single red-irised eye glaring malevolently. Waterfalls cascade from its rising form against a stormy, mountain-ringed lake horizon.
