The first, a jenny. Photo reference for this and the next one are courtesy of the Bureau of Land Management. Their description of her is "#4558 - 6 yr old gray jenny, captured 10/2011, from outside an HMA, California". Outside of an HMA-Herd Management Area means technically she is not protected by the Wild Horse and Burro Act, but she has found her way to a facility anyway. I am not sure exactly how that works, though.
The second painting, this time a jack. His description is "#3952 - 4 yr old gray gelded jack, captured 11/2010, from Cibola-Trigo HMA, Arizona". Both these, and many other burros, are available for adoption throughout the Bureau of Land Management's Wild Horse and Burro program
Both of these paintings are 8X8 in soft pastel on Colourfix Suede. I have decided to keep the jenny, but the jack will be available soon here on the blog!
