Portrait of John Baskerville (1706-1775) James Millar (1735-1805)

The picture has something of this: people, portrait, man, leader, wear, music, jacket, musician, outerwear, elderly, neckwear, poet, theatre, administration, writer.
Perhaps it’s a close up of a painting of a man in a black suit with a white ruffled collar and white hair, holding a cane in his right hand.
