30s vintage black mammy rag doll, cotton feedsack dress, button eyes

1930s vintage cotton doll made with a half body, flat square card bottom under her skirt. A bed doll, or made to sit over something??

She's 6 1/2" over the body, and 14 1/2" overall from the top of her kerchief to the hem of her flowered print skirt. Her face is very detailed, with 'earrings' and round wide pearl button eyes.
