Sao Paulo is the city of the future. In December 2006 the Sao Paulo city council banned all billboards and most other public advertising in the city. Check out the International Herald Tribune article for the full story. You can see the results on Tony De Morco’s flickr site and its truly amazing. When we were in Sao Paulo – it was not only the one of the most heavily bombed cities that we had visited – but one of the most visually cluttered/blighted urban landscapes that we had witnessed – with most of the visual airspace clogged with some of the largest billboards I had ever seen. But now it seems to be an advertising ghost town. It will be interesting to see what the effects if any on the amount of graffiti there will be.
