Just before our nation's birthday in 1976, a group of Marietta women, under the leadership of Sally Hille, organized the Bicentennial Woman's Club. In celebration of the event they collected antique dolls, games, toys, and dollhouses. These were displayed in the Campus Martius Museum, located at Second and Washington Streets in Marietta, Ohio.
In 1989 the expanding collection was moved into two vintage railroad cars located in historic Harmar Village of Marietta. As the collection continued to grow, the museum began looking for a larger space. In 1996 The Children's Toy and Doll Museum purchased their present location. Extensive repairs, renovations, and redecoration were done by volunteers.
