Out of the Inkwell was a major animated series of the silent era produced by Max Fleischer from 1918 to 1929. The series was the result of three short experimental films that Max Fleischer independently produced in the period of 1914--1916 to demonstrate his invention, the Rotoscope, which was a device consisting of a film projector and easel used as an aid for achieving realistic movement for animated cartoons. The Rotoscope would project motion picture film through an opening in the easel, covered by a glass pane serving as a drawing surface. The image on the projected film was traced onto paper, advancing the film one frame at a time as each drawing would be made. Fleischer's younger brother Dave Fleischer was working as a clown at Coney Island, and served as the model for what was to become their first famous character that later evolved as "Koko the Clown."
