The Strange Little Kiosai Saw in the River John La Farge (1835-1910)

The picture has something of this: water, nature, river, ocean, sea, outdoors, sand, beach, park, rock, lake, mammal, wet, landscape, seashore, beautiful.
Perhaps it’s a painting of a woman floating in a body of water with her head above the water’s surface, with a pink flower in the foreground.
