A 300-year-old table built for Queen Mary and used as a Hollywood film prop is to go on sale for more than #500,000, it was revealed yesterday. Buyers from around the world are expected to come to Sotheby's in London to bid for the seventeenth-century side table.It is the only one of its kind and has survived despite being painted for two Cecil B DeMille black and white films. It has since been restored to its original condition though it is unlikely the movie makers realised how rare it was. Sotheby's experts discovered the table, built by British craftsman William Farnborough, in a private collection.
