St. Leonards Festival in Fischhausen on Schliersee in Bavaria Peter Von Hess (1792-1871)

The picture has something of this: people, group, man, woman, mammal, wear, many, vehicle, transportation system, child, veil, cavalry, mountain, herder, seated, landscape, road.
Perhaps it’s a painting of a group of people standing around a horse drawn carriage with a white horse in the foreground and a mountain range in the background.
