This is a JD Kestner doll made in Thuringia, Germany circa 1914. They were in business from 1820 to 1938, but most marked this way are from about 1914 or so. This is doll mold 215 which should be a bisque socket head with plaster under the wig, feathered eyebrows, glass eyes, open mouth and a ball-jointed wood and composition body. These dolls ranged in size form 10" to 42" tall. The letter G means that yours should be 11" to 12" tall and the head a 7 1/2" circumference.
I understand that photos are a pain, so I am giving you a rough idea to satisfy your curiosity and wonder of possible worth. The doll has a value of $150 to $200 retail.
