Benjamin West (fragment from a portrait)

Black and white portrait of a man with a white horse rearing up on its hind legs. The man, Benjamin West, wears 18th-century attire, including a coat and breeches. He looks to the right. The horse's head is turned to the right, with its mouth open and front legs raised. The background is dark and shadowy. The image appears to be a fragment of a larger work, possibly a painting. The style is realistic.
