Ariel Leaving London Docks 1866 J Steven Dews

The picture has something of this: watercraft, ship, boat, sail, sailboat, water, transportation system, sea, nautical, regatta, ocean cruise, mast, schooner, navy, navigation, vehicle, harbor, sky.
Perhaps it’s a painting of a fleet of ships sailing in a body of water with buildings in the background and a blue sky with white clouds.
