A pink javelin signed by Jessica Ennis, a large London2012 Royal Mail stamp autographed by Mo Farah and a Mary Poppins costume from the Olympic opening ceremony are going under the hammer today at an auction in Coventry.
London 2012 chairman Lord Coe described it as a chance for people "to own a unique piece of the Games".
Hundreds of items used during the London 2012 Games are going on sale today, including props from the opening and closing ceremonies and sports equipment.
The sale and auction is taking place this weekend at the Ricoh Arena, which hosted some Olympic events.
The sale takes place between 10am and 6pm today and on Sunday 28 April. The auction of 80 Games and memorabilia items takes place at 11.30am today.
