Sub-Mariner Comics #3

In "The Mystery of the Disappearing Island, Part 1," Sub-Mariner ventures beneath the waves near Ireland and stumbles upon a hidden community of Druids living under domes, their sanctuary now exploited by Nazi forces using their underwater base to launch attacks on Britain. With Alex Schomburg's dynamic artwork bringing the undersea world to life and Harry Sahle's inks adding depth to the action, this early Marvel classic blends wartime intrigue with ancient mysticism in a tale that’s as mysterious as it is thrilling.
