Portrait of the Artist’s Father, Ismael Mengs Anton Raphael Mengs (1728-1779)

The picture has something of this: portrait, people, man, wear, facial expression, leader, profile, music, side view, outfit, writer, outerwear, politician, spotlight, blazer, menswear, musician, light.
Perhaps it’s a close up of a painting of a man in a brown jacket and white shirt with a black jacket over his left shoulder.
