The arrival of Charles II of England in Rotterdam, 24 may 1660 Wouterus Verschuur (1812-1874)

The picture has something of this: watercraft, vehicle, ship, transportation system, sailboat, people, group, warship, military, many, water, navy, sail, flag.
Perhaps it’s a painting of a large group of boats in a body of water with a city in the background and people on a boat in the water in the foreground.
