Ad That Can Be Scratched Off By Commuters

To help promote their latest exhibition, The Museum of Contemporary Art, Chicago came up with a brilliant interactive advertisement that can be scratched off by commuters. Placed at bus shelters, commuters were invited to play archaeologists by unearthing the artworks hidden beneath the ads.

The ads were produced with the help of Classic-Color.
