In honor of The Queen's Diamond Jubilee, the Pictures on Walls website enlisted several top street artists to make a mockery of the occasion in the form of exclusive prints. Most of these "Jubilee Special" releases are now sold out unfortunately, but there does remain one notable exception: Banksy's "Er…" downloadable print, which you're encouraged to grab for free and print on anything you want (for personal use only, not resale). Though you should hurry and get your download, since there is no indication as to how long they will be hosting the image. It's available, currently, at this direct address on their website: http://flag.picturesonwalls.com/er_.jpg
