Dolls from the 1950s chronicled manufacturers' introduction of new materials and new technologies. In dolls made for baby boomers, vinyl and plastic replaced a heavier composition, and rooted synthetic hair, suitable for combing and curling, replaced the mohair wigs of old. Dolls often came with sophisticated new dresses and ensembles that schooled girls in art of high fashion and dressing well. Several companies including Royal, Roberta Doll Co., and Natural Doll Co. carried the fashion doll with the 14-R mold number. The doll appeared when Ideal Toy Company's Miss Revlon was very popular.
