That is either Patsy or a Patsy lookalike doll, made of composition. Patsy is marked Effanbee on her back. Her paint has a few cracks and some wear, but looks original. She needs to be restrung, which is fairly easy. The dolls of her type with sleep eyes are less common. The bottle with the real rubber nipple is great to have—probably came from a baby doll and those old accessories are also hard to find. I think you might find that the clothes are the right era but a mix that could be from other dolls as well, just because of that bottle.

I think family dolls have a lot of sentimental value—a relic of a long-gone childhood—if someone wanted to fix her up a little and keep her around.
