Eric Knowles marvels at a unique piece of street art that covers an entire wall of a building in Southsea, Portsmouth. The Strand city map was originally painted in 1998 and is one of the most famous murals on the south coast of England. Travelling east, two teams of families battle for profits as they shop for antiques and collectibles at a busy antiques fair in Detling, Kent. In red are mum and daughter Louise and Rebecca, guided by expert Catherine Southon. Their opponents in blue are dad and son Steve and Thomas, captained by Mark Stacey. While Louise and Rebecca browse Scandinavian jewellery, Steve and Thomas split their time between looking at both quirky items and big-budget ones. Sharing his estimates on the teams' lots is Portsmouth auctioneer John Cameron. His colleague Daniel Tricker is on the rostrum.
