A customer of mine brought this doll in that was given to her years ago by an elderly lady who she cleaned for when she was a young girl,. This lady is now in her 70's. The doll's body is leather except for her porcelain hands and head.. I can not find another doll like this to compare. It is 11" tall. There is a mark on her back - kind of looks like a crown with ribbons running down.. On one side it has JDK. I did find out that stands for Johann Daniel Kestner. I think the other side says Germany but it is too faint to read. It has the origianal hair- not in great shape. Otherwise she is perfect. I would like to know how old this doll is and what she would be worth. The lady would like to sell her. Any information would be appreciated!!
