We're getting a late start on this year's Jim Lee week - but I think this image more than makes up for it. The original art (seen below) remained unfinished for some years until Scott Williams was commissioned to ink it.
Note Jean Grey's unused costume design - the original art was produced during the time when the X-Men #1 team roster and costume designs had not yet been finalized. This could have originally been intended as a promo piece for the new series.
