(Walt Disney Studios, 1956) Rare original production cels of a Tyrannosaurus rex and lightning effects from The Plausible Impossible episode of the Disneyland television program, which shows the ferocious carnivore limned in white light by a bolt of lightning. This cel was created from the original dinosaur drawing used in the Rite of Spring sequence from the classic 1940 film Fantasia. The cels have been placed on a hand-painted custom background as prepared by Walt Disney Productions. Also included is an alternative color copy background of a darkened sky and forest. Image measures 4.75 x 6.5 (T-Rex), with a mat opening of 12.5 x 9.5. Double-matted to an overall size of 18 x 14. In fine condition. The Plausible Impossible aired on October 31, 1956, as episode eight of the third season of the Disneyland television program. The episode featured Walt Disney explaining how drawings and animation make the impossible seem possible through snippets of ancient history and various cartoons with Mickey Mouse and Donald Duck. An extremely rare and visually striking piece.
