A pair of 6ft-high eyeballs signed by rock band Pink Floyd are being auctioned for charity.
The eyeballs were used at a DVD launch
The props were made to promote the Pulse DVD and will be open to bids on eBay from 14 December, with proceeds going to homeless charity Crisis.
Pink Floyd's David Gilmour, a long-term supporter of Crisis, said extra help was needed in the winter months.
The group briefly reunited with original member Roger Waters for the London Live 8 concert in 2005.
Gilmour said the auction was not just about money.
"The eBay auction will not only raise much needed funds for the charity but will also raise awareness of the plight of the homeless at a time of year when they are most vulnerable."
Crisis will open seven centres in London between 23-30 December, offering homeless or vulnerably-housed people companionship, access to services, learning opportunities and a programme of entertainment.
