Portrait of pianist Wanda Landowska. 1907 Valentin Serov (1865-1911)

The picture has something of this: people, portrait, wear, man, woman, retro, antique, vintage, visuals, paper, design, ancient, wall.
Perhaps it’s a black and white drawing of a woman sitting in a chair with her hands on her knees and her right hand resting on the leg of another woman’s leg.
