Sounds a lot like "Man who gives the war whoop", painted by Paul Kane in the mid 1840's. He was a Plains Cree head Chief in the Fort Edmonton area, as I recall. Portrait in oil aswell as a study done in watercolours is known. Photographers where relatively late coming to the Canadian west. Ca. 1870's. By that time "Man who gives the war whoop" was long dead. I think I have his death year somewhere in my books. Going by memory, it was only a few years after Kane met and painted him.
"Early 1847; Blackfoot attack a Cree camp and kill 4 relations of Chief Kiya Ki Kasakoowe, a close friend of Chief Black Powder" (father of Big Bear). "Fall 1847; Kiya Ki Kasakoowe organises and leads a large revenge party against the Blackfoot; En route the party is struck by ilness, with several deaths. As a result the party turns back". These quotes from J. Fromhold likely refers to the insident where the Chiefs own son was killed and Kane witnessed his riding through a camp with his pibestem calling for warriors to join the retaliation party. Same pibestem as depicted in the painting. A photograph of the pibestem on display in a museum can also be found.
