Grace Martin from the Make Mine Music short "The Martins and the Coys"
I think this is the first Disney redhead.
Image quality is good, but the animation quality was ass compared to what they did 2 years later with Slue-Foot Sue, or had done a decade earlier with Snow White or even Persephone from The Goddess of Spring. She has a second outfit at a wedding dance, but the art is so bad for the 2nd half of the short that her face looks like another character. Wasn't worth using else it'd ruin the entire lora.
