Plot: Michael Aspel and a team of experts examine curios and artefacts offered up by the public in Eston, Cleveland. Exciting finds include a sculpted elephant by Eduardo Paolozzi used to promote floor covering; a Victorian painting bought for five shillings while sheltering from the rain; the first commercially produced toy robot made in the 1930s; a collection of craft jewellery found in an old envelope at the end of a jumble sale; and a fibre-glass chair which Paul Atterbury says is 'an antique for the future'
