After the bath Adolphe William Bouguereau (1825-1905)

The picture has something of this: nude, people, outdoors, nature, water, child, woman, girl, summer, portrait, man, wood, tree, son, park, lifestyle, model, beautiful.
Perhaps it’s a painting of a man with a towel on his lap leaning against a tree with a waterfall in the background and a stream in the foreground.
