So I have to admit to a bias in that I am very fond of the original X-Men team. More so than any line-up since then including Claremont and Byrne's "All New X-Men".
But what really appeals to me about this image by Don Davis is that it has such an old school feel to it.
From the poses, to the expressions on their faces to the bright color that Davis has used, this is the sort of image I can completely see appearing on the cover of a 1960s X-Men comic book.
Old school is not necessarily a bad thing.
