In the 21st century, art market inflation has placed enormous temptations in the way of the old families with substantial collections. In recent years, ownership of several pieces have been transferred in lieu of tax from the Cholmondeleys to the Victoria and Albert Museum. A major sale of items of pictures, furniture, silver and "objets d'art" from Houghton estimated at $23 million was held at Christie's in London on 8 December 1994, with the intention of establishing an endowment fund for the future preservation of the building. Some artwork, such as William Hogarth's portrait of the Cholmondeley family is unlikely to be let go, and it remains on view at Houghton; but the Marquess admits that he is very aware that risk of theft is neither negligible nor negotiable. Jean-Baptiste Oudry's "White Duck," stolen from the Cholmondeley collection in 1990, is still missing.
