This is a vintage Barbie doll from the early 1970s, manufactured by Mattel in Japan. The doll is Skipper, Barbie's younger sister, with blonde straight hair and blue eyes. She has a suntan complexion and bendable legs, and is part of the Sun Set product line. The doll is 9 inches tall and is a TNT doll, which means that her hair can be styled. It is in surprisingly good condition considering its age but does show some minor signs of wear from use. See pictures for more details.
