Following reports that tickets for the Leonardo exhibition are trading on Ebay for hundreds of pounds, the National Gallery has announced that resold tickets will be cancelled, and entry refused. From BBC News:
"We are obviously very disappointed at the resale of these tickets for profit," a spokeswoman said. "The resale of tickets for the Leonardo da Vinci exhibition is against the terms and conditions of their sale and this information is printed on the tickets.
"Our website clearly states: 'Tickets that have been resold will be cancelled without refund and admission will be refused to the bearer.'"
The spokeswoman said the gallery is contacting companies and websites that are accommodating ticket resales, requesting that they "stop immediately".
But she declined to comment on which methods are being used to identify resold tickets.
The last paragraph here is obviously rather important: the sad fact is, there is no conclusive way of detecting who has bought a resold ticket. So there's very little the Gallery can do...
