Sub-Mariner #39

From the depths of Cold War tension comes this 1955 Atlas Comics gem, with cover art by Joe Maneely dropping Namor right into the thick of an underwater showdown. The cover shows a bare-chested Sub-Mariner grappling with armed enemy frogmen — their Soviet insignia clearly visible — around what appears to be an explosive-rigged structure, the murky green ocean backdrop amplifying the stakes. Billed as "his most dangerous adventure," this issue features Bill Everett — sole writer, artist, inker, and letterer — delivering "The Commie Frogmen vs. Sub-Mariner!" at a dime a copy.
