During Frieze Art Fair in October this year, the artists Jake and Dinos Chapman took bank notes from visitors and, before handing them back, "defaced and improved" the money free of charge.

To coincide with the episode How To Get On In The Art World, Jake and Dinos Chapman would like to offer everyone who visits both the Imagine... and Guardian Unlimited websites a free and exclusive piece of art. Come back to download your copy after 10.35pm on Tuesday 20th November 2007. The images will be available for 48 hours only.
