Hertwig & Company, founded by Christoph Hertwig, Johann and Benjamin Beyermann produced porcelain and earthenware objects in their factory in Katzhütte, Thuringen, Germany from 1864 to 1941.
We came across these dolls in Maryland USA, they had been with the same family for many years and we bought them all to keep them together. See others in the same range.
Porcelain doll with white fabric hat, striped apron shorts painted shoes with Germany sign on shoe base similar to Hertwig logo.
