 This film and _Snow White and the Seven Dwarfs (1937)_ (qv) are the  only classic Disney films to use watercolored backgrounds (they were  used in this film because they were cheaper than the gouache and  oils used for _Pinocchio (1940)_ (qv) and _Bambi (1942)_ (qv)) and  the last time they were used until _Fantasia/2000 (1999)_ (qv).
