Thanks to Sue Uhlherr for finding information in the Coleman's Dictionary about some of the early boudoir dolls, made in France, during World War I. It seems that quite a few were made with chamois (suede) faces and silk costumes. According to Coleman's Encyclopedia of Dolls, Volume 2, page 950, these early dolls were referred to as "Poupee Chiffon (Rag Dolls)." Read all the information from the book, below.
This wonderful example has her original painted on silk gown. She has silk floss hair and a stitched chamois face.
