I am a Vintage Barbie and other doll collector and in no way am I an expert. I am thinning out my collection so will be listing quite a few Barbie and other collectable items . Many items I list come from lots I buy and I take a few items out or from local finds. Itry to describe the item to the best of my abilities but may miss something so ask questions if need be. The pictures are part of the description.Returns not accepted but please contact me if there are any issues as I want my buyers to be happy with their purchase.
