This is a set of 4 matted and framed prints from History of the Indian Tribes of North America. The History of the Indian Tribes of North America is a three-volume collection of Native American biographies and accompanying lithograph portraits originally published in the United States from 1836 to 1844 by Thomas McKenney and James Hall. The majority of the portraits were first painted in oil by Charles Bird King. These were professional framed and matted. I am 100% sure if they are just prints or lithographs, but they are highly collectable.
These are images of the following Native Americans.
Wa - Kawn, A Winnebago Chief
Little Crow, A Sioux Chief
Young Mahaskah, An Ioway Chief
On - Pa - Ton - Ga, A Omakas Chief
