The Museum of Automoblies was opened in 1964, and was founded by Winthrop Rockefeller before he became Governor of Arkansas. The museum housed Rockefeller's collection of antique and classic cars until his death in 1973, and in 1975 the collection was sold to collector Bill Harrah for $947,000, which included 68 motorized vehicles and three that were horse-drawn. The museum building, designed by the Little Rock firm of Ginocchio, Carter, Cromwell and Neylan, and 57-acre grounds were donated to the Arkansas Department of Parks and Tourism.
