For anyone who owns an iPad, I highly recommend this iBook about graffiti: Henry Chalfant’s Graffiti Archive. It catalogs New York City subway graffiti in the 80s … the start of Hip Hop! Whether you are into art history, street lore, social sciences or even if you simply like the images, this iBook is really cool.
