Bridal Homecoming at Lake Hornavan Johan Fredrik Höckert (1826-1866)

The picture has something of this: water, people, seashore, watercraft, vehicle, beach, sea, ocean, group, recreation, landscape, transportation system, calamity, man, storm, military, fisherman.
Perhaps it’s a painting of a group of people on a boat in a body of water next to a hut with a flag on it and a mountain in the background.
