Auction

Everyday is different in the world's greatest auction houses. In this fascinating series we cover the huge range of art treasures which go under the hammer in London, Paris and New York. From the art of the Polish eccentric Tamara de Lempicka sold for $6 million in Manhattan, to the 1941 Jean Prouve bicycle - now a design icon - bought by a collector in Paris for 70,000 Euros.
