Kirby continued layouts for the cover of X-MEN for quite a while after giving up the interiors, though I’m not sure about all the ones he’s credited with. This one, finished up by interior artists Werner Roth and Dick Ayers, seems like a pretty safe bet, though. I like the pose of Professor X in the flashback scene to his awesome origin.
And that’s one really big and well labelled bag of money…
