Sub-Mariner #59

Two of Marvel's mightiest monarchs collide on this striking 1973 cover, where Namor and Thor square off in a clash of royal fury — fists raised, hammers swinging, neither willing to yield an inch. Jim Starlin's pencils and Bill Everett's inks bring tremendous kinetic energy to the confrontation, with the dialogue bubbles perfectly capturing the defiant pride of both warriors. "Thunder Over the Seas" promises exactly the kind of head-to-head showdown the cover so vividly delivers.
