Once upon a time, virtually all of the major Hollywood studios were producing animated shorts. Walter Lantz, of course, was long associated with Universal. WB & MGM had their own animation houses. For a while, so did Columbia.
Over the course of 7 years, Columbia nurtured their own funny animal comedy team, The Fox & the Crow, before they were shipped off to UPA. Legendary director Frank Tashlin helmed their first effort, 1941's "The Fox & the Grapes", but he left for WB and forged his legacy there. Bob Wickersham took over, and is at the controls for 1942's "Toll Bridge Troubles":
Crawford Crow and Fauntleroy Fox also appeared in comics, debuting for DC in 1945, and staying their through the mid-60's. However, their animated shorts haven't seen the light of day in what seems like forever. They were last seen on television more than 50 years ago, when a syndicated package included them with either Hanna-Barbera's Ruff & Reddy (H-B was a Columbia subsidiary at the time) or Total Television's King Leonardo. I'm not even sure if these shorts are even available on DVD presently.
