A camera used by Usain Bolt to take photographs in the wake of his men's 200m victory at the London 2012 Olympics is up for sale.
Sports photographer Jimmy Wixtröm has listed his Nikon D4 on eBay, with bidding reaching $11,200 (£6,917) by midnight ET (5am UK time) on Friday (October 5).
Bolt used Wixtröm's kit to take pictures of other photographers and of his teammate Yohan Blake, which were then published by Aftonbladet.
The athlete has etched the words "Bolt #1" into the top of the camera body using a screwdriver.
"My girlfriend's father passed away far too early due to cancer, and my brother Peter is thankfully now completely recovered after suffering from cancer and undergoing treatment for more than a year - thanks to the great progress that has been done in cancer research," Wixtröm wrote in the auction description.
The 16.2 megapixel professional-grade DSLR camera has a recommended retail price of £5,289 in the UK and $5,999.95 in the US. Wixtröm's camera will be sold alongside a framed 50cm x 70cm print of one of the photographs which Bolt took at the Olympic Stadium in Stratford, east London.
The auction closes on Tuesday, October 9. Proceeds from the sale will benefit the Swedish Cancer Society and the Usain Bolt Foundation, which supports children and young people in Jamaica.
