I think so, but Advertisers pay money to have wall space - graf doesn't! Unfortunately, money speaks and the therefore advertising is what we will see on our walls for a long time to come :(

Yes. As stated by folks below - urban spaces are dreary sites of abusive advertising monolgues, and drastically need to be humanised by art.

In terms of governments fostering urban art, I think their job is to get out of the way. If the idea that such acts are crimes is dropped then I think on a whole its for the 'people' to then get creative. I'm not against some inidividual government initatives per se but I think people can do amazing things independent of government. Great story

I love the concept of "reverse-graffiti", in our day and age it's good to see people making art out of our rubbish - it has great potential to raise awareness for pollution.

I've been to Brazil. Its an amazingly beautiful country, the city however is not so much the same, especially when you get to the outer suburbs. Yet the urban jungle has raised some very skilled and creative people and art. Whether government should foster urban art or not is matter of opinion but look what has been produced so far. Simple pleasures to distract people from their life situations, to bring a smile to the face and others like the reverse -graffiti to awaken others and make you think(which I loved!). Great Story!!!!
