1981 Fisher Price "My friend Becky" doll

1981 Fisher Price "My friend Becky" doll. Only includes what she has in picture. She has beautiful red hair that appears to be in really good condition still. She does have small black mark on right hand that most likely would come off. I'm unfamiliar with older dolls and didn't want to chance messing her up trying to clean it. I have acquired a small doll collection that I am trying to get rid of. I have limited knowledge on antique dolls and collectibles so please be patient as I sort through & research them enough to be able to list.
