Winold Reiss was a German-born American artist and graphic designer. In 1920, he went West for the first time, working for months on the Blackfeet Reservation in Montana, painting 36 portraits of tribal members. Over the years Reiss painted more than 250 works depicting Native Americans. These paintings by Reiss became known more widely beginning in the 1920s to the 1950s, when the Great Northern Railway commissioned Reiss to do paintings of the Blackfeet which were then distributed widely as lithographed reproductions on Great Northern calendars. In 1931, and 1934-37, Reiss organized a summer art school, also referred to as an artists' colony near Glacier National Park. The Great Northern Railway was an American railroad running from St. Paul, Minnesota to Seattle, Washington from 1889 to 1970 when it merged with three other railroads to form the Burlington Northern Railroad which after additional mergers in 1996 became the Burlington Northern and Santa Fe Railway.
