(Walt Disney Studios, 1929) Remarkable and hugely desirable original production background from The Karnival Kid, the ninth ever Mickey Mouse animated short film, with a custom-prepared hand-painted cel depicting Mickey as a hot dog vendor at a carnival, with Kat Nipp, a barker at the carnival, standing on a platform nearby with his arms akimbo; this cel was made later by the Disney Studio for a display at a 2001 Ronald Reagan Museum exhibit. The custom cel is placed on the original hand-inked and -painted production background from The Karnival Kid, which is marked "Scene 7" in the lower border. Character images measure 5.25 x 5 (Mickey and cart) and 2.75 x 5 (Kat Nipp), with overall dimensions of 11.75 x 9.5. In fine condition. Accompanied by a certificate of authenticity from Ron Stark of S/R Laboratories, who affirms that this cel and background set-up was "proudly displayed in 'Walt Disney: The Man and His Magic,' May 13 to September 4, 2001, at the Ronald Reagan Presidential Library and Museum." In addition to its fantastic imagery, this important background derives from a notably historic Mickey Mouse cartoon: The Karnival Kid was the first cartoon to feature Mickey speak ('Hot dog! Hot dog!') and the scene where Mickey tips his ears to Minnie inspired storyman Roy Williams to invent the Mickey Mouse ears hat.
