Old vintage antique all bisque German child doll

From a doll collector Estate here is a wonderful 5" tall all bisque doll marked 5701 and a number 1 on the back. I do not know the maker of this little doll, I imagine she is from the early 1900s. Little gal is jointed at the shoulders and hips having blue painted stockings with black molded shoes. Pretty face with UNUSUAL blue eyes, I do not think they are glass, they look like a shiny stone with painted pupils? Please see photo #9. There are long painted lashes around the eyes, brown brows and little mouth with a space between the lips. She wears a gorgeous brunette mohair wig, attached to a pate. I see no cracks on the head. Doll has fingers all intact. She wears a little yellow knit dress with attached panties. I have taken plenty of photos, please look at my photos they will serve as part of this description. If you would like further pictures or have any questions, concerns please email me. Doll is being sold as is condition with NO reserve auction. Serious bidders only please. Estimate shipping cost in the US would be $5.50 by priority mail, outside the US please email for shipping cost. I use plenty of bubblewrap and package well. Please note that Import duties, outside US taxes and charges are not included in the item price or shipping charges. These charges are the buyers responsibility.  Thank you and Good Luck! I do COMBINE shipping and will be listing her family & friends all week.
