The final episode in this series has a suitably festive theme. Griff Rhys Jones and his teams of experts - historians Janina Ramirez, Kate Williams and Hallie Rubenhold and ceramics expert Lars Tharp - visit the V&A Museum of Childhood. Originally founded as a museum for the East End area of London, today it houses the largest collection of childhood objects in the UK and will provide a seasonal challenge for Griff and his guests.
