Otto von Bismarck Franz von Lenbach (1836-1904)

The picture has something of this: people, portrait, wear, man, side view, music, leader, facial expression, outerwear, administration, veil, profile, scientist, facial hair, outfit, elderly.
Perhaps it’s a painting of a man in a black suit and white shirt with his hands in his pockets and his right hand in his other hand and his left hand.
