No person shall write, paint or place with ink, paint, chalk or any
other substance or substances or otherwise mark, carve, scratch or etch graffiti
on the real or personal property of another, whether real or personal property
publicly or privately owned, unless the owner of such property shall have
prior knowledge of such writing, painting or placing of graffiti and subsequently
consented to the same.
The marking of any property, real, personal or mixed, by an owner thereof
in such a manner as would constitute graffiti is likewise prohibited.
