Gathering Kelp at Newlyn Harold Harvey (1874-1941)

The picture has something of this: cavalry, people, mammal, seated, group, carriage, man, transportation system, skirmish, cart, weapon, lid, war, lithograph, chariot, veil, horse.
Perhaps it’s a painting of a man riding on the back of a brown horse next to a group of people on a rocky beach with a dog laying on the ground.
