The Antiques Roadshow welcomes visitors to Derby's Roundhouse, a vast railway shed that dates back to the golden age of steam, where finds include a portrait on a pillowcase, a chilly Russian paperweight and the world's earliest football trophy. Fiona Bruce introduces a show that takes place inside the world's first and oldest surviving railway roundhouse, where dozens of trains were once serviced. Entertaining finds include a pair of Clarice Cliff bookends won in a pub darts tournament, a silver christening cup with a surprising history and a portrait by a renowned British artist - painted on a fragment of a pillowcase in a prisoner-of-war camp. A silver claret jug awarded to Hallam Football Club in 1867 also makes a return appearance in the Antiques Roadshow Uncovered feature, as recent research leads silver specialist Alastair Dickenson to believe it could be far more valuable than first thought.
