Sub-Mariner #30

On a sun-drenched beach, a visibly conflicted Namor crouches in a fighting stance — muscular and defiant yet internally torn — while Captain Marvel challenges him from the shoreline, demanding he come out and fight. Sal Buscema and Mike Esposito give the scene real dramatic charge, with the cover blurb "If Namor Falls… A World Must Die!" hinting at stakes far larger than a simple beachside brawl. Roy Thomas and Sal Buscema deliver a 1970 Marvel adventure that pits two of the era's most formidable heroes against each other under circumstances Namor himself dares not explain.
