CMR was a great artist, he did not work for money, he worked because he had to, he was an addict. A pencil and piece of paper, even an old grocery sack or chalk and a sidewalk or some clay and he would have created his work.
Most artists seem to run with women who have no understanding or appreciation of their work and make very poor choices for their partners.
Nancy Russell came into his life, pretty much dominated him and made him recognized as a star. Her book is a good one also.Without her I feel there would be very little known about Charles M Russell.
Frank Linderman played a heavy roll also, I think.
