X-Men WildC.A.T.s

This promo image for the X-Men WildC.A.T.s crossover is among Jim Lee's last official X-Men work.

He drew some covers for the crossover, and he drew issue #2, which featured the Neal Adams era X-Men.

Jim Lee and Scott Williams

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.

George Perez - Avengers 178 - Updated!

There are quite a few differences between this unpublished cover for Avengers 178 featuring the Beast and the published version, both by George Perez.

(Professor H. and Tom Brevoort have both brought it to my attention that the published cover is by John Buscema.)

Captain Britain and Psylocke

From the Deviant art page of Mark Brooks:

"Just something done for fun in the last couple of days. I've always loved these characters sice back in the day and thought they would fit perfectly for my country series of pics. the first was the Silver Samurai with the Japanese flag behind him. next I plan on doing a few more including Colossus from Russia, Wolverine from Canada and, of course Captain America. 
For anyone not familiar with the characters, Capt. brit and Psylocke are siblings born in England. Psylocke is a member of the X-Men and Captain Britain is one of the founding members or Excalibre. Pencils and colors by me."

Captain Britain Week

According to Wikipedia:

In 2001, a four-issue limited series titled Excalibur, featuring Captain Britain, Meggan, Psylocke, Black Knight, Sir Benedict, Captain U.K., and Crusader X, and written by Ben Raab, detailed Captain Britain's rise to become king of the extra-dimensional realm of Otherworld.

Originally solicited as Excalibur: Sword of Power, the subtitle was absent from the published issues, and, due to an error, the indicia described it as Excalibur volume 1. In addition, the solicited cover to issue #1 featured a new costume for Captain Britain, different from the one he actually received in the comic, and the cover was unused
