Woman with white stockings Gustave Courbet (1819-1877)

The picture has something of this: nude, people, shirtless, man, son, tattoo, sexy, portrait, strength, athlete, brawny, strong, naked, thorax, kneeling, wrestling, woman.
Perhaps it’s a painting of a woman sitting on the ground next to a body of water and holding a piece of paper in one hand and a red shoe in the other hand.
