RARE Black Doll with White Updo antique and similar items

I have done extensive research on this doll. She was made in German (no makers mark that can be found at this time) around 1880 to 1910. She is Bisque porcelain, with hand made clothing. She has her dress, petticoat, and bloomers (old fashioned underwear). Her hands, arms, legs, feet and shoulders/head are all bisque. She is the porcelain doll to follow flat-top china dolls, so her hair is a great research for aging the doll. This style was mass produced from a mold, but not many were made in black skin tones. Also, back then the skin for black dolls was one color: Black. They did not understand browns. So this doll because it was made from a mold that was used for white dolls, it looks very "European" in features, note the blue eyes which is another sign of the time frame it came from. The eyes not glass. Two condition issues are noted on this doll, one the forehead and the second the left hand. The hand is shown in picture 3, and is not there. There is also a small chip in the glaze they used on her forehead which shows off the actual color of the bisque porcelain. Please follow up with me on any further questions. These dolls were not brought to this country until the latter portion of the 20th century due to vile Jim Crow laws occurring in the US at the time. This doll is part of our history even though it was made in Germany.
