I didn't know anything about this artist...here's a few "selfies" that he took way back when! LOL!
Joseph, Baron Ducreux (26 June 1735 – 24 July 1802) was a French noble, portrait painter, pastelist, miniaturist, and engraver, who was a successful portraitist at the court of Louis XVI of France. His less formal portraits reflect his fascination with physiognomy and show an interest in expanding the range of facial expressions beyond those of conventional portraiture.
