Collected publications of Banksy

Recently I've noticed a lot of Banksy articles are being published in London newspapers such as London Metro, London Paper and Lite.. I've collected a few and scanned them to use them as another artist that could support my topic in my written paragraphs on being 'anonymous' as well as being a graffiti artist himself. And yet this artist has become famous when nobody has seen his face properly while his works are everywhere in public. In addition to that, he is famous because of vandalism but yet again it is art that people like to see and buy. This is when the question comes up: Is graffiti Vandalism or Art?
