Paul Vallotton, the Artist’s Brother Félix Édouard Vallotton (1865-1925)

The picture has something of this: people, portrait, wear, man, menswear, leader, neckwear, outfit, dinner jacket, jacket, facial expression, cravat, tie, confidence, music, outerwear, vest.
Perhaps it’s a painting of a man in a black suit and tie with a cigarette in his hand.
