Lyon Playfair Henry William Pickersgill (1782-1875)

The picture has something of this: portrait, people, wear, jacket, man, menswear, outerwear, neckwear, musician, leader, music, writer, outfit, facial hair, administration, vest, eyewear, eyeglasses.
Perhaps it’s a painting of a man in a tuxedo sitting in a chair with a book in his hand.
