One of the last surviving Union flags from the Battle of Trafalgar to come up for sale at Treasure House Fair

A Union flag from the Battle of Trafalgar, flown on the Royal Sovereign under Admiral Cuthbert Collingwood, is being offered for sale at the Treasure House Fair for £450,000. The flag, newly identified by expert Martyn Downer, is one of only three known Union flags from the battle and is believed to be the most important such relic still in private hands. It was previously sold for a few hundred pounds in 2003 due to confused provenance.
