If you can’t find Red Carolinians, PM me & I’ll send ya an extra copy I have here. With one caveat: when you’re done with it, donate it to a Carolina library that could use it.
Two artists (both white) that you may want to look up for the “picture’s worth a thousand words” factor are Charles Bird King and George Catlin.
Charles Bird King (1785-1862)painted the portraits of many Indian chiefs and members of their families who were delegates to D.C. from any number of tribes. Google his name and you’ll find many of his works, and there are books of his art as well. Hollywood rarely got the clothing right for Indians and the Indians who lived east of the Mississippi were given little treatment at all. Here in the Southeast where you had so many “half blood princes” of the Choctaw, Chickasaw, Cherokee, Creek and Seminole their clothes often reflected their mixed heritage- they loved colors and often wore bright color jackets, ostrich feathers in addition to the traditional turkey and eagle feathers, uniforms, but also buckskin and moccasins to ‘accessorize’. Other chiefs and tribes wore almost exclusively their own tribal fashions because they wanted as little to do with the whites as possible. King is one of the best sources we have as to their appearances.
(He also painted white patrons and landscapes, but his Indian artworks are his most famous, and this is the portrait I’m relatively certain he would have made of me 
.)
George Catlin went west with William Clark (of Lewis & fame, but this was many years later) and did a series of watercolors of Indian villages and festivals and landscapes. Also considered one of the great artistic primary sources of Indian life.
I enjoyed “The Earth Shall Weep” by James Wilson as a broad, introductory survey. I read it a while ago and don’t remember a ton of it, but for some reason a single paragraph from the introduction has stuck with me fiercely (go figure, right?). It was about the racialized application of certain terminology (i.e. soldier vs. warrior, king vs. chief, etc.) and was brief but has had a lasting effect on how I read history.
A couple of recent books look interesting, although I haven’t read either yet: Cahokia: Ancient America’s Great City on the Mississippi by Timothy Pauketat and The Comanche Empire by Pekka Hamalainen.
