Welcome to the board, Cindy.
If you are shopping on e-Bay for a Kit, there are several people here who will help you identify if she is fake or not. Good luck!

The x on the doll or furniture means that it came from the MCM sale. The MCM sale is a once a year charity event that AG donates their defective, out of date and returned dolls to. It is held in July in Madison, Wisconsin. Even though they are not supposed to, some people buy a lot at the Madison sale and sell it on e-Bay. If a doll has an x on it, it cannot be returned to AG. It also may not be 1st quality.
