Celebrities and others have donated signed items in support of Andy Nation's 147 mile swim from Teddington to Calais last year in aid of Herts Air Ambulance and Hertfordshire MS Therapy Centre.
Andy undertook the swim a year later after breaking his neck and being temporarily quadriplegic in 2012. A documentary tells the whole story. 100% of the money raised will go to the two charities.
The items are listed on the swim website and are being sold/auctioned to the highest bidder.
