The Rival Generals fording the Ujigawa Utagawa Kuniyoshi (1798-1861)

The picture has something of this: water, sea, ship, boat, watercraft, ocean, people, sun, vacation, marine, leisure, sail, summer, man, sailboat, nautical.
Perhaps it’s a painting of a group of people on a boat in a body of water with mountains in the background and a sky with clouds.
