nature #248 Rien Poortvliet (1932-1995)

The picture has something of this: landscape, tree, dawn, outdoors, winter, weather, fall, sheep, fog, cavalry, mammal, nature, countryside, wood, fair weather, mist, sunset, environment, agriculture.
Perhaps it’s a painting of a couple of cows in a field with trees in the foreground and a man on a horse on a hill in the background.
