Paul Fischer Bedende Kvinder (A Morning Dip) Paul Gustave Fischer (1860-1934)

The picture has something of this: water, people, man, fun, river, two, woman, leisure, beach, seashore, nature, vacation, lifestyle, wet, nude, girl, outdoors.
Perhaps it’s a painting of a group of naked people standing on rocks in a body of water with rocks in the foreground.
