Weird Tales Jan 1945 – Serpent Princess Underwater Fantasy Cover

While actual deep-sea exploration would later involve unglamorous submersibles and pressure suits, this cover imagines a diver encountering glowing green serpent-women in an otherworldly underwater realm. A helmeted diver in full brass diving suit brandishes a weapon at a towering emerald Serpent Princess, flanked by smaller supernatural female figures amid fire-like seaweed and red starfish. This is quintessential weird fiction pulp — mythology, menace, and barely-clothed supernatural women colliding in lurid, dreamlike color.
