Adonna Combs of Columbus, a commercial artist, said her 9-year-old horse, Justin, began painting two years ago when she noticed him using her riding whip to draw in the sand and she attached a paint-covered brush to the end of the whip, WDBR-TV, Louisville, Ky., reported Tuesday.
"It just made sense to tie a brush on the end of the whip, so I did. And to my surprise he kept painting. He kept making those brush strokes," Combs said.
Combs said the paintings have sold for $75 to $2,500 and buyers have contacted her from as far away as Denmark, Austria and Australia.
She said one of the animal's most unique works is a red splotch that resembles a horse.
"And I told everybody about him painting a self portrait, everyone is skeptical and then they see it and say 'It is a horse!'" Combs said.
