The Art Car Boot Fair celebrates its fifteenth anniversary. This year it is hosting it's annual event in Granary Square in Kings Cross. The concept of the show is all of the artists personally pitching up and selling their original, exclusive artworks at astonishing just-for-the-day prices from the back of cars. This is the ideal place for entry level collectors to find a bargain. In the past original works by Damien Hirst, Grayson Perry and Tracey Emin have sold for under £100.
