Advances in animation which developed during this period explain the astonishing illusions which emerged in these comedic shorts. In the 1930s he directed It's a Bird, his first sound film. Bowers returned to animation for advertising films, in particular the first short film by Joseph Losey, the oil-commissioned Pete Roleum and His Cousins, while also continuing his puppet films. He died in 1946, completely forgotten.
To this day, 11 of the 20 short comedies are still considered lost. At the end of the 1960s, vault discoveries provided more of his story and three of the exhumed films were shown in 1976 at the Annecy Animated Film Festival, where they were met with enthusiasm. After 1992, worldwide research retrieved surviving prints of the missing films with requests to the world's notable cinema collectors, who allowed access to their original elements. For the first time this extraordinary collection assembles the complete films of Charley Bowers which survive today, magnificently restored from the original elements with the collaboration of ten cinema societies.
