The Royal College of Art has announced that its charity postcard auction, RCA Secret, has received 2900 artistic contributions this year - a record for the annual event.
Contributors to the event - where every postcard costs £45, but the artist is unknown until the purchase has been made - this year include artists Tracey Emin, Grayson Perry, Anish Kapoor as well as design figureheads James Dyson, Paul Smith and Kenneth Grange.
RCA Secret 2011 opens on 18 November, with potential bidders able to view the art online or in person in advance of the sale day on 26 November. The sale itself begins at 8am and runs until 6pm, with each piece sold on a first come, first served basis.
