Charles Marion Russell
A Mix Up

One of the best animal painters in the world is Charles M. Russell, of Montana, who is popularly known as the cowboy artist. His specialties are frontier scenes, wild Indian life, cattle pieces and natural history subjects, all of which are... embued with a truthfulness of character and detail which is possible only for those... who are to the manner born.
