Auction

A new season of Auction includes fine jewels, mid-century furniture, wine, collectables from the world of showbusiness, and classic cars. In this programme, Sotheby's sell The Lock by John Constable. It's a copy of the original by Constable himself. He liked it so much that he kept it in his studio until his death. Will it fetch eight to twelve million pounds? Elsewhere, Coy's sell a replica of Ralph Lauren's 1930s Mercedes-Benz.

Everyday is different in the world’s greatest auction houses. In this fascinating series we cover the huge range of treasures which go under the hammer.

Two of the most ornate and valuable tabletops have come to London from the collection at Warwick Castle. Valued at half a million pounds each, they were commissioned by a noble family of Venice but later sold to the Earl of Warwick. In one of the most unusual sales of recent times with just two lots the 'Grimani Tables' represent a gamble for Sotheby's. Will they sell? Also in this programme, fine jewels are up for sale in London as is memorabilia from the world of entertainment including the blouse Judy Garland wore in the film The Wizard of Oz.

A life at auction - items from the collection of the late Dowager Duchess of Devonshire come under the hammer at Sotheby's in London. Deborah Devonshire was the youngest of the Mitford sisters and her lifelong work, after she married Andrew Cavendish, was to restore the great stately house of Chatsworth. Elsewhere, prints and multiples are offered at Christie's and there's a new perspective of art from the Cold War, painted by artists working behind the Iron Curtain.

It is one of the oldest and most remarkable auctions in the world. In Burgundy they gather to sell off this year's wine en primeur, in aid of the Hospice de Beaune. It's a tradition started in 1795 but the hospital that the wine sale supports dates back to 1443. This year, the sale has an added poignancy; it takes place just hours after a terrorist attack in Paris.

In Staffordshire, Bonham's are selling rare motorbikes and you don't get rarer than a set of eight Brough bikes discovered in Cornwall. Made famous by Lawrence of Arabia, these bikes are being described as the discovery of the century. In complete contrast, the London saleroom of Christie's is selling Old Masters.
