“This horse are wild horse/ Chars. Willis” (Artist’s inscription, verso)

“A herd of wild horses is the subject of this drawing. The compactness of the herd, and the proximity of the horses one to another, is indicated by their placement, one behind the other. This is a convention of Plains Indian painting. Also traditional is the lack of a ground line and landscape elements. The great speed of the horses is indicated by their extended legs.” (p.48)
