Really old Barbie doll 1960’s but older-

This vintage Barbie was actually my mother‘s. She believed it to be one of the first release from the black-and-white swimsuit era, but I cannot confirm this sweet Barbie doll does not have Venable legs was manufactured in Japan and does not have holes in her feet nor does she have the green staining on her ears. Her hair is in the original styling. The red outfit is not the original, but goes with the Margarette boots. I can provide additional photos as needed her hair soft as well as her bangs. She has been uncleaned and unaltered. I am in no desperate position to sell my mother‘s doll, but would love to see her end up in someone’s collection who has a true passion for these dolls. I have additional madam Alexander pieces. *CAT NOT INCLUDED
