While I don't think it is ever okay to deface property, I do think that some forms of graffiti are very artistic. That was the inspiration for an ATC swap I'm hosting on Paper Traders. My rules were that it must be hand-drawn and not contain any profanity or nudity. These are the cards that I made. I colored the letters using a combination of oil pastels and Marvy markers... and a lot of elbow grease with my paper stumps.
