Le guepier Adolphe William Bouguereau (1825-1905)

The picture has something of this: nude, people, water, child, woman, man, recreation, leisure, girl, sea, outdoors, swimming, son, love, baby, shirtless, summer, fun, enjoyment.
Perhaps it’s a painting of a woman in a blue dress with angels on her back and a man laying on the ground in front of a group of her.
