Behind the scenes

Lancelot Thwaytes of Penrith sold the painting in 1996 for £42,000 through Sotheby's as being a work by a follower of Caravaggio. Its new owner, Sir Denis Mahon, has decided that it is by the master himself and is therefore worth £11 million - well he would, wouldn't he?

Mr Thwaytes is of course a bit cross about this turn of events and is suing Sotheby's for failing to research the work properly.

Either way it is a contemporary copy as the real painting of 'The cardsharps' is at the Kimbell Museum in Fort Worth.
