Portrait of Leon Bakst. The second half of 1900 Valentin Serov (1865-1911)

The picture has something of this: people, portrait, man, wear, veil, facial hair, facial expression, retro, vintage, lid, leader, mustache, bill, outerwear.
Perhaps it’s a painting of a man with a hat on his head and a tie around his neck, sitting in front of a wall and looking off to the side.
