A Collection of unpublished or rarely seen art from Marvel's X-Men Comics. This blog will also feature promotional art, commissions, alternate covers, and trade paperback & graphic novel covers.
From a U.K. reprint title, I couldn't locate any information on the artist.

That's early Jim Cheung; he used to do a lot of covers for Marvel UK back then. That's his signature at the bottom left.
