This has to be the best graffiti we've seen in a long time, it was in a side street in Barcelona. Might be some angry printers protesting about the rise in the use of RGB images and less four colour process hard copy due to the internet! We were trying to work out how they did it because it was quite high up on the wall, you can't really tell from this image, but it's quite big. Balloons maybe, must be a good shot though! If anyone can tell us, please do...
