This cartoon was colorized in 1992 by Turner Entertainment Company, with each frame traced over onto a cel. Each cel was then painted in color and photographed over a colored reproduction of each background.
Redrawn in the 1970s for the "When Funnies Were Funny" TV show. Retitled "On Duty". There was no dialog in this version, as well as replaced music and SFX because the source was silent.
