Koko the Clown was an animated character created by animation pioneer Max Fleischer. The character originated when Max Fleischer invented the rotoscope, a device that allowed for animation to be more lifelike by tracing motion picture footage of human movement. To test out his new invention Fleischer photographed his brother Dave in a clown costume. After tracing the film footage amounting to some 2,500 drawings and a year's work, Koko the Clown was born. In 1931, Koko was taken out of retirement and became a regular in the new Fleischer Talkartoons series with costars, Betty Boop and Bimbo. Koko's last theatrical appearance was in the "Betty Boop" cartoon, "Ha! Ha! Ha!" (1934), a remake of an "Out of the Inkwell silent, "The Cure" (1924). Koko's first color appearance was a cameo in "Toys Will Be Toys," (1949), one of the revived "Screen Songs" series produced by Famous Studios. The colorized version of Koko also made a cameo appearance in the ending scene of Who Framed Roger Rabbit. In 1958, Max Fleischer set out to revive Out of the Inkwell for television, and a series of 100 color episodes were produced in 1960 & 1961 by Hal Seeger using the voice talents of Larry Storch.
