Resting Cows. Motif from Öland Nils Kreuger (1858-1930)

The picture has something of this: mammal, water, animal, wildlife, two, cattle, nature, people, river, cavalry, outdoors, livestock, wild.
Perhaps it’s a painting of a couple of cows laying on top of a grass covered field next to a body of water with a sky and clouds in the background.
