X-Men #140, page 1 by John Byrne & Terry Austin. 1980.
John was shown this page and he shared a story about it being, “the last straw” before he quit the X-Men:
Every issue there would be what I called my “ARGH!!” moment, when I came across something Chris had written that went against what I had drawn, or what we had plotted. The cumulative effect was numbing to say the least. Here I went “ARGH!” on the very first page. Can you tell why?
Specifically, it was the way I had drawn Colossus easily ripping that stump out of the ground, replete with flying clumps of earth and speed lines versus the way Chris scripted it. I saw that page, printed, and just threw up my hands. “Can’t do this any more!”
I called Weezi (then the editor of Uncanny ) the same day, to resign.
