Grafitti in public spaces has been defined as a form of visual communication. Sometimes it is no more than scribbles on a boxcar or water tower or door. On such sites, there is no artistry and it serves only to deface.
On the other hand, grafitti can be an art form in which case it never fails to catch my eye.
Often the canvas is an aluminum door behind which may be a commercial space.
The door may be an eyesore in an abandonded warehouse that attracts a creative soul who vastly improves its environment.
Always I wonder at the inspiration behind such creations and about the person(s) who are responsible.
Certainly, there is talent displayed and while all grafitti artists may not have the good fortune to be discovered as was Basquiat, their creations do enhance the blandness of many a urban landscape.
