Portrait of William Murdoch (1754-1839) John Graham-Gilbert (1794-1866)

The picture has something of this: people, portrait, man, jacket, wear, leader, outerwear, writer, pants, neckwear, poet, mustache, furniture, administration, music.
Perhaps it’s a painting of a man in a black suit and white shirt sitting in a chair with a book in his lap and a candle in his hand.
