Offered in this lot is a coloured lithograph of the Herman Heyn photograph, "Waiting, Two Mounted Sioux", 1899. The same lithograph is featured at the National Museum of the American Indian, "Lithograph of Lakota men in traditional dress on horseback, ca. 1890." Herman Heyn (1866-1949) was an important portrait photographer in Omaha, Nebraska, from the 1880s through the 1920s. He is nationally noted for more than 500 images he created of Native Americans, mostly Sioux, in 1898 - 1899, and particularly portraits of people at the Indian Congress of 1898 in Omaha, Nebraska. The Indian Congress, part of the Trans-Mississippi International Exposition (World's Fair), drew more than 500 participants representing 35 tribes. With $45,000 in federal funding, it was in part intended to showcase what was considered by some a fading culture. And so evolved the idea of a project taking portraits at a modern-day pow wow - because after 100 years the culture has not ''faded away'' - and to record that moment in history with the same casual dignity that is found in Heyn's earlier portraits. The colouring was most likely hand-coloured to the original photograph as was done to many of Heyn's photographs, though it is unknown if Herman or his older brother George did the colouring.
