This is an original cel and background set-up from the Marvel Studios production of the Mojovision episode of X-Men: The Animated Series. This setup features a key matching image of Mojo yelling at Longshot with Dazzler in the background, and was created at the studio and used during production. The overall measurements of the piece are 10.5" x 15.25" and the image itself measures 11.5" x 9". The piece is in very good condition.
The artwork was published in the book "X-Men: the Art and Making of the Animated Series" and appears on page 132.
