Portrait of Joseph Jennens (1769-1848) Thomas Phillips (1770-1845)

The picture has something of this: portrait, people, wear, man, neckwear, jacket, menswear, facial expression, outerwear, coat, outfit, leader, woman, music, tie, fashion, side view, model.
Perhaps it’s a close up of a painting of a man in a black suit with a white shirt and a white tie and a black jacket.
