Portrait Of Furst Otto Von Bismarck Franz von Lenbach (1836-1904)

The picture has something of this: people, portrait, man, wear, leader, elderly, side view, scientist, music, facial expression, facial hair, veil, administration, exploration.
Perhaps it’s a painting of a man in a black suit and white shirt with his hands folded in front of his chest and his right hand resting on a cane.
