today we will ride to the country of the Great Plains horse people, where winds will never stop blowing.
in the past I pointed to the so called ledger drawings as the best source for the Plains Indians history, imagery and fine example of graphic storytelling done by the horse warriors themselves. My favorite Great Plains tribe, the Cheyennes, had some very fine artists skilled in telling the stories of their exploits.
The Plains Indian Ledger Art website has digitalized 15 Cheyenne ledgers (11 Northern Cheyenne and 4 Southern Cheyenne) and one ledger of the Southern Cheyenne/Arapaho origin.
I would like to point your horse - :) - towards this still great book - ''The Fighting Cheyennes'' by George Bird Grinnell.
George E. Hyde, titled 'Life of George Bent: Written from his Letters' (1967) or this one, that is not very trustworthy - David Fridtjof Halaas, and Andrew E. Masich, 'Halfbreed: The Remarkable True Story Of George Bent.')
Bellow find three reviews written and published in respectable research journals already in 1915-16,
James Mooney - The American Historical Review, Vol XXI, Oct 1915-July 1916
