Shot by Harry Pollard, a prominent studio photographer in Calgary, these photos capture members of several First Nations around Alberta and western Canada.

Among the groups represented are the Tsuu T’ina, whose population had dwindled to just a few hundred at the time of these photographs and has since rebounded to more than 2,000 individuals.

Also included are portraits of the Siksika, Kainai, and Piikani, the three “original people” of the Blackfoot Confederacy, a group of related nomadic nations who traditionally hunted bison across the vast plains of northwestern America and Canada but were forced to settle on reservations by the start of the 20th century.
