Giant Mermaid Holds Submarine, Fantastic Adventures March 1950

A submersible vessel — representing cutting-edge deep-sea military technology — is dwarfed to toy-like scale in the grasp of a colossal underwater woman, blurring the line between myth and science fiction. This Fantastic Adventures cover illustrates Alexander Blade's 'The Mermaid of Maracot Deep,' depicting a glamorous, shell-necklaced giantess rising from a lush undersea coral garden, casually clutching the ill-fated submarine as air bubbles drift past her in an otherworldly teal abyss.
