MAYBE READ THE ARTICLE FIRST
The thing I don’t understand with people treating street art like this is that was not it’s original purpose. Street art always evolves, comes and goes, its there then it disappears. Treating it like something sacred doesn’t that loose what you find it appealing in the first place? But one thing is for shore that it does bring it into the public eye and people are now paying more respect to this art form rather than just dismissing it as something that is a public nuisance.
Update : Check out what has now happened to this Street at this post.
