glrx-1539 Friedrich Gauermann (1807-1862)

The picture has something of this: mammal, outdoors, desert, nature, tree, landscape, wildlife, mountain, rock, park, cavalry, sky, daylight, antelope, wild, scenic, cattle, two.
Perhaps it’s a painting of a group of cows standing in a field next to a tree and a man with a dog on the other side of the painting.
