I do not profess to be a Barbie Doll expert but from my research this doll appears to be as described below. Further it has the information on the butt cheek and also has the number 6. If this is not the doll, please let me know, thank you.

This is a stunning vintage 1961, Barbie Bubblecut doll from Mattel is in excellent condition and was manufactured in Japan. The doll has curly raven black hair, blue eyes and light complexion. This set includes 2 pieces, with the doll being 11.5 inches tall and the original swimsuit. The doll is original and licensed. This is a must-have for any Barbie collector, especially those interested in vintage Barbie dolls from the 1960s.
