"The Cowboy Artist" Charles M. Russell, who once worked as a cowpuncher, infused his work with details that only an artist with experience on the open range could capture. His paintings are prized for their genuine and sophisticated depictions of the American West's fading wildness.

A traveling exhibition, "Masterworks of Charles M. Russell: A Retrospective of Paintings and Sculpture," is now at the Gilcrease Museum through May 2.  Denver Art Museum curator Joan Carpenter Troccoli edited a lavishly-illustrated and comprehensive catalog with multiple essays by Russell scholars.

The exhibition travels to the Museum of Fine Arts, Houston, in June.
