Aquaman (1962-1978) #55

Join Aquaman in a battle at .00000001 feet! With the help of Vulko, Arthur has returned to the mystically microscopic world within Mera’s ring to save an old ally. Meanwhile, Aquagirl faces a battle not of powers and weapons, but of hearts and minds. Then, in an electrifying second story, Aquaman finds an underwater ghost town—but ghosts might not be the only monsters lurking in the shadows.
