Issue Tagline: SUB-MARINER and Magneto's Evil Mutants--Partners in Menace Against The X-MEN! / Also: DAREDEVIL in... The Mystery of The Man With The Mask! / And Beginning This Issue... The INCREDIBLE HULK!
This is the first appearance of a Hulk story in this title. When the comic ceased being a giant-sized book with #32 the Hulk would share it with Sub-Mariner for awhile before finally taking it over entirely.
Only reprints the Huilk story from Tales to Astonish (1959) #60.
