WHISTLE
STEAMBOAT WILLIE
First Mickey Mouse cartoon
(1928)
Animation drawing of the third steamboat whistle in its tall “open-mouthed” position. On a full sheet of two-hole punched animation paper, 9 l/2 x 12”.  Artist: Ub Iwerks.  Numbered 1—the first drawing of the whistle in the film—has some discoloration along the bottom and on right side, probably from being the first drawing with part sticking out of a folder.
