This is only the far left of a wide picture don by Bev Doolittle called "Two Indian Horses". The original is a wide print of many horses in a row resting with a Second Calvary soldier walking off in the other direction. (Pinned above) My all time favorite of her work. Brilliant artist!
"Pintos" by Bev Doolittle print first issued for $65.00 in 1979, now selling for over $10,000 if you can find one.
