Female Nude With Raised Arm Félix Édouard Vallotton (1865-1925)

The picture has something of this: nude, shirtless, man, naked, brawny, sexy, people, body, strength, topless, fine-looking, biceps, thorax, son, torso, portrait, fitness.
Perhaps it’s a painting of a nude woman with a hat on it’s head and a body of water in the foreground, and a light blue sky in the background.
