Portrait of Dominique Vivant (1747-1825) Baron Denon Robert Lefevre (1755-1830)

The picture has something of this: people, man, portrait, wear, indoors, administration, education, writing, business, music, writer, furniture, facial expression, election, document, school.
Perhaps it’s a painting of a man in a tuxedo holding a book in his right hand and looking at the viewer with a smile on his face.
