Motorcycles built by the Milwaukee-based company from its inception in 1903 until the suspension of civilian manufacturing at the outbreak of World War II are the most prized bikes among motorcycle collectors. Color photography of restored models features such classics as early singles and twins, World War I military models, racers, Flatheads and Knuckleheads. These early Harley-Davidsons also inform the inspiration for many of the aesthetic touches, including paint schemes and logos, on Harley-Davidson's modern offerings. Included in this history is a remarkable, never-before-published prototype drawing from 1901.
