Final issue. "From the Void It Came...," A brooding Namor gets into a confrontation with a couple of surface dwellers; They attack Namor which leads to a fight; Then he's attacked by an alien creature; The defeated creature escapes and Namor is left to wonder its purpose. Closing notes by Roy Thomas. NOTE: Aquaman #56 and Sub-Mariner #72 is the infamous hidden DC/Marvel crossover! Writer unbeknownst to the editorial staffs of Marvel & DC, creates the very 1st crossover between the Big Two. Aquaman battles a creature that at the end of the issue explodes in outer space. Years later, the same creature emerges in the Marvel Universe from an explosion in outer space. This has to be one of the most underrated gems in Comics History. $0.25.
