Lays "Walkers" but for the rest of the world

This is an ad campaign for 'Lays' USA, they are trying to advertise that their potatoes are 'grown closer than you think' and Lays 'chips' or crisps, are made with local potatoes. It's a clever idea to use the roof of the subway tunnels, to show the potatoes growing through as you are underground. For three weeks in this subway tunnel in Chicago you will be able to see this installation of potatoes falling through the ceiling due to the creative minds of the Juniper Park agency in Toronto. It's another one of those ambient media campaigns that just works. It reminds me of the two amnesty international campaigns; 'It happens not here. But now' and the poster campaign were they put all the faces behind bars. These three campaigns have one important thing in common, the placement of the advertisement is the main contributing factor to the idea being successful.
