Aquaman #15

From DC's June 1964 run comes this eye-catching issue featuring Aquaman and Aqualad ensnared in what appear to be powerful, swirling metallic coils — straining against their bonds above an eerie underwater cityscape glimpsed at the bottom of the cover. A taunting speech bubble demands to know why they struggle, promising that being chosen to inhabit someone's "Undersea City" should be an honor. Nick Cardy's cover art delivers fluid, kinetic energy that makes the duo's predicament feel genuinely urgent, with the churning underwater currents practically leaping off the page.
