“Jake and Dinos Chapman […] will spend much of the fair [Frieze art fair at Regent’s Park in London] sitting at the stand of their gallery, White Cube. Hand them any kind of English paper money - […] anything so long as it has the Queen’s head on it - and they will draw on it for you. They’ll give you back the note, now worth many times more than your original outlay, and with the monarch’s visage defaced.” (story)
