This is a 1989 Baby Denton by Horsman.
She is 17" tall and vinyl. She has sleep eyes, drinks and wets, and is washable.
She is adorably dressed in a pink Dr. Denton sleeper.
It even has the drop panel.
She is one of the dolls I purchased, hoping that she would be my beloved childhood doll. She isn't quite right, but really, really close.
