Art or not?

Barry Heintz pulls the trigger of a powerwasher to blast away the last vestiges of an eight-foot-long and two-foot-high sprawl of graffiti in a Mount Vernon alley.

If it's your canvas, it's Art!
If it's someone elses, it's Graffiti!
Graffiti is a drag on Society and a drag on Art.
Toon Dip for the perpatrators!

A tag is someone name? Someone name is a signature? Signatures are not art. If your an artist use proper mediums to do art. A public or private wall, train, truck, and other surfaces are not proper. Art is in the eye of the beholder but a signature is just you name.
