This is an original production cel and background set-up from the Marvel Studios production of the X-Men episode, Old Soldiers. This production cel and background set-up features Captain America and Wolverine and was created at the studio and used during the production of the film. The overall measurements of the piece are 10.5" x 12.5" and the image itself measures 10.5" x 12.5". The cels and background are stuck together, but they are properly registered, and look fantastic as they are shown here.
The artwork was published in the book "X-Men: the Art and Making of the Animated Series" and appears on page 234.
