Artist Tomas Georgeson says he's left a cheque for £8,000 in Milton Keynes Gallery in the hope it will attract more visitors.
He has placed an advert in the local newspaper, The Milton Keynes Citizen, which reads: "A blank cheque for £8,000 has been hidden somewhere in the public spaces of Milton Keynes Gallery. It will be collected on 1 March 2013 if unclaimed."
Mr Georgeson said he wanted to get people through the door and change the mood of the place.
