Holly Hobbie was a rag doll that was dressed like a prairie girl from the early 20th century. She usually wore a blue bonnet and a matching dress, and wore her brown hair in two braids. She seemed to be popular in the 70s and early 80s because I seemed to have plenty of Holly Hobbie stuff including two Holly Hobbie dolls (one being a smaller replica), a sewing maching, and a cash register. I think I might have even had a Holly Hobbie bed set.
Holly Hobbie was actually the name of the character's original writer and illustrator. Hollie Hobbie (the character) originally began life as a series of illustrations for American Greetings, however, following great sales on the cards Knickerbocker Toys licensed the Hollie Hobbie character for a line of rag dolls.
