Here is a beautiful sketch by O. C. Seltzer, the Great Falls artist. He calls it "An Artist of Yesterday."  The Indian sign writer is telling with his crude pigments, the narrative of the buffalo hunt of his tribe.  The imprint of the hoofs of the horses indicate the direction in which the hunters went to find the buffalo, which spelled food, sustenance and clothing.  Following the hunters came the squaws, with the travois, who must dress the kill and take the meat back to the Indian encampment, portrayed at the extreme left of the sign writing.  In a number of places in Montana these cliff records of a forgotten age tell the story to the initiated of Montana before the white man came.
