(Walt Disney Studios, 1928) Original production drawing featuring Mickey Mouse from Steamboat Willie, showing the iconic mouse's head and arms with drum mallets. Accomplished in graphite and colored pencil on untrimmed 12 x 9.5 animation paper, marked "502" in the lower right corner. Image measures 4.25 x 5. In very good to fine condition, with tears to the side edges. During a wonderful musical sequence, Mickey cheerfully opens a bull's mouth to play percussion on the oversized teeth. A remarkably early and desirable production drawing from the debut of Mickey Mouse, and the first Disney cartoon to feature synchronized sound.
