The Secret Postcard Auction returns for 2015, where works by celebrated artists are auctioned off.
Last year's event saw works from renowned names including Grayson Perry, Tracey Emin and Damien Hirst, but the idea is that you won't know who's behind the postcard until after the auction has ended. You never know - it might be a Turner Prize winner!
The ticket price includes drink and nibbles, and can be booked online here.
