Fiona Bruce presents the show from Clissold Park in Stoke Newington. Treasures include a collection of ancient Peruvian pottery, with some pieces made over a thousand years ago, an archive of textile designs by pioneering post-war designer Althea McNish, and Harold Wilson's pipe. Ceramics expert Serhat Ahmet challenges Fiona to work out what she should buy, sell or keep from a selection of figures by the Meissen factory
