Q: I won this stunning 21-inch composition Margaret O’Brien doll by Madame Alexander at an auction. The original owner had purchased the doll new in the original box with the clover wrist tag that said Margaret O’Brien. For some reason, the previous owner discarded the box and the wrist tag but kept the doll in a glass cabinet. Her son had put the doll up for auction. She is flawless, and the dress is tagged Margaret O’Brien. I also have a Margaret O’Brien Madame Alexander doll in hard plastic, and I was wondering when the change from composition to hard plastic occurred?
