Each year, the Royal College of Art displays and sells over 2,500 original postcard-sized artworks created by their students and professional artists and designers. The artworks are sold anonymously for £45 each to raise over £1 million total for the RCA Fine Art Student Award Fund. Famous artists like David Bailey, Tracey Emin, and Nick Park have donated pieces in past years. The secret is that buyers don't know the identity of each artwork's creator until after their purchase, so it involves an element of luck, but discovering emerging talent is part of the fun of the event.
