Emanuel Gottlieb Leutze – Mrs. Schuyler Burning Her Wheat Fields on the Approach of the British Los Angeles County Museum of Art (LACMA)

The picture has something of this: people, group, mammal, child, herder, cattle, woman, man, livestock, two, farming, cavalry, recreation, cropland, wear, three, girl, son, outdoors.
Perhaps it’s a painting of a group of people in a field with a dog in the foreground and a black dog on the other side of the painting.
