Dancing Figures Concept
----- DATABASE NOTES -----
From “Make Mine Music: Blue Bayou (1946). A concept pastel on purple, 5-hole paper. The concept shows two dancers outside next to a fountain. Small pin holes in upper left and upper right. May have been an inspiration for some of the ghost scenes in Disney’s “Haunted House” attraction. Originally created for Fantasia to accompany “Clair de Lune.” [Item: 9"W x 7-7/8"H] Acquired 2000.
