Aquaman #5

This October 1962 DC issue plunges readers straight into oceanic menace, with Nick Cardy's cover depicting a pair of massive, spell-wreathed killer whales bearing down on Aquaman and Aqualad as the two heroes struggle in the churning surf below. In the background, a robed sorcerer raises a blazing trident, the apparent source of the supernatural energy crackling around the whales — and a speech bubble from the heroes warns, "That evil sorcerer cast a spell over these killer whales — they're coming for US now!" Featuring the King of the Seven Seas alongside his young ally Aqualad in "The Haunted Sea," this is Silver Age DC adventure at its most visually dramatic, with Cardy's dynamic linework making the threat feel genuinely urgent.
