His military prowess not only gained him celebrity among the Lakota people, but also among white artists and ethnologists.

In 1884, American artist DeCost Smith[8] was compelled to paint him due to his accolades.The warrior-artist is best known today on account of music ethnologist Frances Densmore (1867-1957) who had interviewed Jaw in 1911/1912 and was the recipient of several of his works.
