Jean-Baptiste Greuze – Portrait of an Artist (Portrait of the Architect Ange-Jacques Gabriel; Self Portrait) Part 3 Louvre

The picture has something of this: people, portrait, leader, man, elderly, writer, wear, music, scientist, woman, royalty, side view, administration, engraving.
Perhaps it’s a close up of a painting of a man in a black suit and white shirt with a book in his hand and a pen in his other hand.
