Mermaid and Faun, the beginning of the twentieth century. Corners Sergey Sergeyevich Solomko (1867-1928)

The picture has something of this: people, woman, girl, two, nude, man, water, recreation, lithograph, group, portrait, beautiful, child.
Perhaps it’s a painting of a man and a woman sitting on a rock next to a body of water with rocks in the foreground.
