Carte de visite Paul Frecker This portrait shows Princess Pauline with her husband, Prince Richard Metternich, the Austrian ambassador to the court of Napoléon III. The carte-de-visite was copied by Degas for his portrait of the Princess (cropped at the waist, and with her husband omitted altogether) which now hangs in the National Gallery, London, one of the earliest known examples of an artist basing a painting entirely on a photograph.
