The Battle of Copenhagen 2 April 1801 J Steven Dews

The picture has something of this: ship, watercraft, boat, transportation system, sea, sail, sailboat, water, navy, ocean, nautical, sky, ocean cruise, navigation, frigate, harbor, warship, wind.
Perhaps it’s a painting of a fleet of ships in a body of water with a blue sky in the background and a white cloud in the middle of the sky.
