Today's redrawn, Cinderella, was originally a 1936 Techicolor cartoon called Once Upon A Time, produced by Audio Productions for Metropolitan Life Insurance. This cartoon features a charming original song, with music by Edwin E. Ludwig and words by Frank W. Speidell.
This R&TVP cartoon is, IMHO, one of the worst-looking redrawns I've ever seen. Have fun spotting the mistakes when comparing it to the original:
