Vintage 1967 MATTEL 3577 Family Affair BUFFY & Mrs. Beasley DOLL Sealed

This listing is for a Buffy and Mrs. Beasley set made by Mattel. It was sold to me about 25 years ago as NRFB and has been displayed since then. Unfortunately over the years the right arm and hand has darkened a lot. I really don’t know what caused it. Maybe the wires inside the doll? Also Buffy’s left pigtail looks a little disheveled. Still a cute set with all the parts.
This item comes from a non-smoking home. Please feel free to message me with any questions or requests for additional photos.
