ceci n'est pas...

a street art project based on the famous Magritte painting of a pipe inscribed, "Ceci n'est pas une pipe" (This is not a pipe). These posters depicted common grocery items with the tagline "Ceci n'est pas...un poisson, un limon, un'orange etc" The website was "howdoyouknow.com" and was based on the concept, how do you know what you know.
