Elk Albert Bierstadt (1830-1902)

The picture has something of this: deer, mammal, antler, buck, wildlife, stag, animal, moose, bull, horn, velvet, antelope, nature, reindeer, grass, rut, zoo, grassland.
Perhaps it’s a painting of a red deer with antlers on it’s head standing in a grassy field with a blue sky and clouds in the background.
