Portrait of the Artist Lawrence Alexander Peter Brown Giovanni Boldini (1842-1931)

The picture has something of this: people, portrait, man, jacket, wear, mustache, facial hair, outerwear, lid, coat, pants, music, vintage, veil, model, painter.
Perhaps it’s a painting of a man with a beard sitting in a chair with his hands on his knees and his right hand on his left side of his leg.
