Vintage 1976 Mattel Ballerina BARBIE Doll Bendable TLC

This is a vintage 1976 Mattel Ballerina Barbie doll with bendable limbs and Twist 'n Turn features. Her hair is not in the original style but it is still very shiny and soft. She has a mark on her nose and neck, but she’s gorgeous. Her hands and feet appear to have been chewed on either by a dog or child. She has marks all over her limbs. Her legs are a bit loose. She has a rough mark on her shoulder. Her dress has stains on it and may possibly be ripped, I am unsure how the leotard is supposed to be so not sure if that’s manufactured. She is missing one of the snaps on the dress so it doesn’t close. There are loose threads on the arm holes.
