Lapps Collecting Reindeer which have Been Shot Johan Tiren (1853-1911)

The picture has something of this: mammal, people, group, man, weapon, skirmish, war, military, cavalry, herder, soldier, two, gun, livestock, army, seated, child, cattle, hunter.
Perhaps it’s a painting of a group of people sitting in a field next to a white horse with antlers on it and a dog laying on the ground.
