Bill Everett biographer, Blake Bell, has a photograph of Everett coloring this cover. The original Gil Kane version of this cover had the Outcast as villain, but was rejected by the Comics Code as being too frightening. The Juggernaut's face replaced the Outcast, and is likely a Werner Roth stat with Romita touch-ups. Iceman is also redrawn/revised by Romita with possible Brodsky inks. Information provided and updated by Nick Caputo, July 2012. The original indexer credited John Tartaglione as inker.
