While I am not a portrait photographer — I specialize in landscapes and color abstracts only — I was struck by these remarkable early portraits of members of several First Nations around Alberta and western Canada photographed by Harry Pollard circa 1910.
As the Mashable article also highlights, “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.”
