Christie’s holds four sales of Old Master Drawings every year: New York (January), Paris (March), and London (July and December). With sales that include drawings by artists who worked in Europe between the 14th and 19th centuries, we have offered works by Michelangelo, Boucher, Ingres, Goya, Garner, and Watteau, among many others. Our sales coincide with the annual Old Master weeks in New York and London in January and July, respectively, while our Paris sales are held during the week of the Salon du Dessin, ensuring the broadest possible international audience.
Estimated sales: 3 per annum
