Terry Austin’s cover for Uncanny X-Men # 142, and a colored reprint of John Byrne’s unused cover for the same issue.

If memory serves, John Byrne’s original cover art for Uncanny X-Men # 142 was lost by the Canadian post office. Terry Austin ended up doing the pencils and inks for the cover that got published. By the time John Byrne got the artwork back, the issue had been published already, so a pinup was all that came out of it.
