#08646 Thomas Eakins (1844-1916)

The picture has something of this: people, portrait, man, mustache, leader, wear, lid, neckwear, menswear, facial hair, vest, politician, scientist, music, side view, jacket.
Perhaps it’s a painting of a man in a black suit and white shirt sitting in a chair with his hand in his pocket and a cane in his other hand.
