This doll is almost 24 inches (60 centimeters) tall. She is marked with a "50" at the pate rim, and has additional markings on the back of her shoulder plate: Made in / Germany / K&K / 60 / Thuringia. Her bisque head was made in Germany and imported to the United States (some time between 1915 - 1925) where it was combined with the rest of the doll parts by the K&K Doll Toy Company, which was owned by the George Borgfeldt Company.
The doll has a bisque head, composition arms and legs, and cloth body with a non-working round cry box. She appears to be stuffed with a darkish material, so I think it is wool felt. Notice that her knees still retain the rosy blush. (See a primer on doll making materials at www.justaboutdolls.com/material.html)
Her composition is in remarkably good condition, as is her bisque head and cloth body. There is glue residue on her head, where someone was a little too enthusiastic in their application of wig glue. She is missing her original pate, and in it's place there is a neatly glued round of cardboard that was cut from a box that once held envelopes. She has two small holes in the back of her head, and holes at the bottom of the front and back shoulder plate. The shoulder plate has been glued to the cloth body. In the photo below, you can see the museum's accession number that has been written on her back. You can also see where the doll stand has indented her body. (She's now been removed from that torture.) She has stitching at the hip level, which allows her to sit nicely, although of course, without any knee joints, it is an awkward straight-legged look. Because she has straight legs and not bent legs which are typical of baby dolls, it is generally agreed that she is depicting a young toddler.
The long wig is human hair and styled with a center part and long sausage curls. The wig base has been cut so that it will fit on her head. For this reason, I do not think it is original. It is not glued down, but the beanie hat holds it in place.
