1st appearance of Professor X, Cyclops, Beast, Iceman, and Marvel Girl. 1st appearance of Magneto! X-Men cover and story, Stan Lee and Jack KirbyVery solid book which might be an upgrade candidate. No chipping!
1st appearance of the Vanisher! 2nd appearance of the X-Men! 7.0/7.5 structure but has a piece of old tape at bottom, so I've knocked it down about 2 grades, X-Men cover and story, Stan Lee and Jack Kirby
