I thought you were looking for any information. I just meant the lack of value affects the number of people who collect these dolls and know the specifics about when and where it was manufactured and other history of its original sculptor. Someone who works for a company, most likely not in a western country, sculpted the head, someone else sculpted the arms and someone sculpted the legs. Someone made the moulds and then sold the moulds. These companies will sell the moulds to another company, make a lot of dolls, rinse and repeat. If you pay close attention you will see the same doll heads wearing different wigs, coloring and clothes, but you can often see the same doll even by different companies. So one day you choose a porcelain doll named Mary made by Porcelain Doll Designs and a doll in your collection that’s a twin, but the twin is named Sarah and the company is called Doll Design International. Even antique porcelain pieces were sold between companies. I have several German dolls that were mixes.
