Henry Moore’s seminal work King and Queen will be a highlight at Christie’s 20th/21st Century: London evening sale on March 5. It has been in the same British collection for the past 70 years. Conceived in 1952–53, the sculpture was first cast in an edition of four plus an artist’s cast. This is the only remaining example still in private hands; all other casts are held in major public collections, including the Moa Museum of Art, Atami; the Hirshhorn Museum and Sculpture Garden, Washington D.C.; the Middelheim Museum, Antwerp; and the Norton Simon Museum, Pasadena. Two subsequent casts were produced specifically for the Tate Collection (1957) and The Henry Moore Foundation (1985). The estimate is £10 million – £15 million.
