Original hand-painted model cel of Mason that was used during the production of the second part of the "Two-Face" episode of Batman the Animated Series. The piece also includes the original xerox model sheet of Mason with hand-written notations for the color call-outs that were used to paint the model cel. These pieces were reference materials used by the ink and paint department to ensure consistent character design. The untrimmed cel measures 12.5" x 10.5" with the line work on a separate cel layer from the characters paint. The model sheet measures 8.5" x 11" overall. The image of Mason on both pieces measures 6.5" x 4" and the art is in excellent condition.
