Brueghel, Jan (I) – Gezicht op een stad aan een rivier, 1600-1630 Rijksmuseum: part 1

The picture has something of this: watercraft, water, boat, ship, transportation system, sea, vehicle, sail, group, sailboat, vacation, people, river, ocean, summer, fisherman, harbor.
Perhaps it’s a painting of a group of boats in a river with a town in the background and people on the other side of the boat in the water.
