The series is the result of three experimental short films Max Fleischer produced independently in the period 1914-1916 to demonstrate his invention, the rotoscope, which was a device made up of a movie projector and a stand used as an aid to obtain realistic movements in cartoons. The rotoscope projected a film through an opening in the stand, covered by a glass plate acting as a design surface. The image on the projected film was drawn on paper, advancing the film one frame at a time as each drawing was made. Brother Dave Fleischer was working as a clown at Coney Island, and served as a model for what became their first famous character, Koko the Clown.
