I have a very early (considered rare) My Twinn doll. She has the Jessica face mold and if you do any research (go to Logan's Ladies online) you will see that she is wearing an original dress from the first year of manufacturing. She is in perfect condition without shoes or underwear. I hate to part with her, but own way too many special dolls and am clearing out some of them. She is 22 inches tall and would make a good "sister doll" for an American Girl doll.
She was a popular option when American girl dolls were still in 25in the early years.
