| Notes | Bill Everett biographer, Blake Bell, has a photograph of Everett coloring this cover. This cover is a mixed bag. The original cover featured the Outcast as villain, but was not approved by Comics Code. Juggernaut face/figure is perhaps a Werner Roth stat, with alterations by Romita. Iceman figure is by another artist. Remainder of cover is by Kane. |
