Audi RS 6

I think that this ad campaign is really clever by Audi. I don't know how clear the photo is but basically Audi have placed ads in front of Speed Cameras saying "Say Cheese". (The Audi RS6 is a fast car). The concept behind the ad is clever and humorous. It would be great to see the advert looking more like a road sign though.... don't know about the legitimacy though!
