Olympic medallists Lizzie Armistead and Ed Clancy are among the celebrities who have designed bicycle helmets for a charity auction at Sotheby’s today.

The Celebrity Bicycle Helmet Auction II is celebrating the first year of The Legacy List, a charity set up to ensure a post-London 2012 Games legacy in arts and education.

The specially commissioned helmets include contributions from London 2012 competitors Armistead, who won silver in the women’s road race, and Clancy, who won a gold in the team pursuit and a bronze in the men’s omnium.

Other helmets which will be available to the highest bidders at the auction house in New Bond Street have been designed by people including fourth plinth artist Yinka Shonibare and artist Michael Craig Martin.

Money raised from the auction will ensure that arts, culture and education play a central role in the legacy of the future Queen Elizabeth Olympic Park and its surroundings.

The auction will be introduced by the UK Minister for Culture, Communications and Creative Industries, Ed Vaizey.

Auctioneer Olivier Barker will offer 18 lots in Helmet Auction II. The first celebrity helmet auction, held when the legacy list launched a year ago, included a helmet designed by London Mayor Boris Johnson.

The Legacy List was set up by Mr Johnson and the London Legacy Development Corporation (LLDC), the body in charge of the Olympic Park after the Games.

The charity will work to make sure high quality cultural and learning programmes are an integral part of the future of the Olympic area. Its work already includes an architect-designed green Play-Space, a local theatre, a summer Art Camp and a poetry award for schools in the six Olympic boroughs.

Mr Johnson said: “We want the park to become a must see destination, attracting visitors from around the world, helping to create more jobs and support the economy. The Legacy List was set up with the support of my office to help develop these opportunities and your support of this charity will help us to raise money to help deliver that vision.’

Sarah Weir, chief executive of The Legacy List, said: “Since last year’s auction, we have already developed a range of imaginative post games artistic and educational projects which build on both the creativity of the permanent art commissions in the park, as well as creative talent already in the area and beyond.”
