Bosko, the Talk-Ink Kid (1929)
Bosko, the Talk-Ink Kid is a 1929 live-action/animated short film produced to sell a series of Bosko cartoons. The film was never released to theaters, and therefore not seen by a wide audience until 2000 (71 years later) on Cartoon Network's television special Toonheads: The Lost Cartoons. The film was produced in May 1929, directed by Hugh Harman and Rudolf Ising, together with Warner Brothers. Ancient times was considered lost, but a copy found in the studio missing only beginning and the end.
