Giant Octopus Attacks Submarine, Wonder Stories June 1932 Cover

A deep turquoise undersea world explodes into menace as a massive dark octopus wraps its tentacles around a bulbous red submarine, its porthole windows revealing the terrified faces of trapped passengers. Fish dart through the luminous blue-green water above while a sailing ship ghosts the distant surface. The vivid crimson of the vessel against cool aquatic tones creates electric contrast, perfectly capturing the breathless terror of S.P. Meek's story 'Trapped in the Depths' in pure pulp melodrama.
