Portrait of William Pitt, standing three-quarter length in a Dark Jacket and Breeches John Hoppner (1758-1810)

The picture has something of this: people, portrait, man, wear, jacket, leader, outerwear, music, indoors, coat, outfit, authority, lid, facial hair, pants.
Perhaps it’s a painting of a man in a black coat and white hair wearing a white collared shirt and black pants and holding a cane in his right hand.
