John Singleton Copley (1738-1815) – Watson and the Shark, 1778 (National Gallery of Art, Washington, D. C.) part 2 American painters

The picture has something of this: people, group, man, watercraft, woman, recreation, water, fisherman, weapon, transportation system, child, three, vehicle, war, four, wear, skirmish.
Perhaps it’s a painting of a group of people on a boat in a body of water with a shark in the foreground and a ship in the background.
