Graffiti treasure trove

There's a street in Villa Madalena, a neighbourhood in western São Paulo, that has been given over to graffiti artists. The work there is extraordinary - orginal and striking, with identifiable elements of the art's roots mixed with Brazilian sensibilities of sex, politics and nature. My favourite mural at the site, a kind of triptych, incorporates all these themes into its imagery and even manages to fully incorporate an actual tree. The first picture below is from the middle section of the piece, and I've added a few more below that. There are about 25 pics of other works in the Trip do Brasil flickr set.
