Street art: Paste-ups of Kingston

I’m a fan of street art. I’m not talking about mindless tagging and vandalism of private property, although I’ll admit there’s a fine line between them. I do think it’s possible to distinguish between good and bad however, and what I look for is something that catches the eye, causes amusement, creates a feeling of whimsy or just makes you stop and pause unexpectedly. I guess I see the value it can add to some otherwise bland and somewhat desolate urban spaces.
