(Disney, 1982) An original Ektachrome continuous-tone transparency cel of Dumont, the Tower Guardian, and Yori from "Tron." The Ektachrome cel was created at the Studio and used during the production of the special effects sequences in the film. The groundbreaking film predated modern-day computer animation, requiring the unique lighting effects to be hand-created frame by frame. This painstaking process was only used for "Tron," making the film's effects artwork a special piece of Disney and cinema history. Measuring 12" x 20" overall, the cel is in very good condition with minor surface scratches and general handling wear.
