Unterberger Franz Richard Motio Du Lac Du Garda Franz Richard Unterberger (1838-1902)

The picture has something of this: people, vehicle, group, water, transportation system, dawn, watercraft, sunset, recreation, fisherman, man, landscape, evening, two, outdoors, river, reflection.
Perhaps it’s a painting of a group of people sitting on a rock next to a body of water with a boat in the water and a mountain in the background.
