Watch for Cars
Upon seeing this billboard, this graffiti artist appears to have been let down. Watching cars and being a safe driver didn’t seem as entertaining as seeing a show. As a result, they added a little sardonic remark to warn future motorists that they would not be viewing an exhibition in the parking lot.

We have to confess. This one isn’t as clever as some of the other graffiti on this list. Obviously, we’re watching for vehicles rather than a show while driving. But oh well, they can’t all be diamonds.
