Just this small note about a great art book, Wall and Piece from the "anonymous" street artist : Banksy. Instead of wasting money in crappy product, the art book is really a nice buy and clearly politically engaged. I liked the following tag next to a big flag : "people who enjoy waving flags don't deserve to have one". If you want to see more, just have a look at the banksy tag in flickr. A book to have in your art-book shelve.
