Heya guys... Have a couple of questions about Street Art/Grafitti and this seems to be best place I can find to ask it... I have a big 3m x 3m wall at the front of my house in Melbourne where I'm thinking of getting someone to do some interesting street art/grafitti - possibly something similar to Banksy... A couple of questions - Anyone know of any legal issues - would I need a permit? and also if It were well done would taggers respect it or is it likely to encourage them?
