In early August, during the Sturgis Motorcycle Rally in Sturgis, SD, the role of motorcycles in American culture will be recognized on four “American Motorcycles” stamps featuring digital illustrations of a 1918 Cleveland, a 1940 Indian Four, a 1965 Harley-Davidson Electra-Glide, and a circa 1970 chopper. The Cleveland, Indian and Harley-Davidson stamps are based on motorcycles in existence today. The circa 1970 chopper featured on the stamp was created by stamp artist Steve Buchanan in consultation with professional chopper builders.More information USPS commemorative stamp program
