The American Girl Catalogue Began as a Concept to Introduce

The American Girl catalogue began as a concept to introduce girls who lived in the past to today's girls.Each historically accurate doll is carefully crafted and dressed and has books to describe her life.For example,Kristen is an 1854 pioneer girl who is growing up in Minnesota.Her story begins with her long sea voyage from Sweden.The basic doll dressed in a calico dress and striped apron and the hardcover story of how she got to Minnesota cost $90.Six more hardback books of Kristen's life are available for $80.Kristen's nightgown costs $20,and a matching one for the doll owner is an additional $40.Buy both together and the price is only $50.A hand-painted wooden bed and trunk for Kristen are available for $220.Shipping costs vary with the price of the merchandise ordered and are not connected to weight or distance.
