I hear of an ingenious way to circumvent admission charges to museums. This autumn - not for the faint-hearted - the Schirn Kunsthalle in Frankfurt is staging a 'unique and challenging' exhibition, called 'Blood:
Perspectives on Art, Power, Politics and Pathology'. Parked outside the entrance will be a blood donor van. Any visitor donating blood will be given free admission to the exhibition. Don't tell Tessa Jowell.
