Vilhelm Hammershøi (1864-1916) – Seated Female Nude Kobenhavn (SMK) National Gallery of Denmark

The picture has something of this: people, nude, man, sculpture, statue, shirtless, portrait, naked, son, leader, marble, Renaissance, strength, ancient, figure, monochrome.
Perhaps it’s a painting of a naked woman sitting in a chair with a hat on her head and a white shirt on her body, with a gray wall in the background.
