Streetpost art

Earlier this year, I was walking back to work from lunch on Elgin street. I came across this interesting sight:

Someone (or perhaps a bird) had picked away at the inch-thick layer of staples surrounding this telephone pole. Here's a closer-up view.

At the next post up the street, I saw this little work of art, leading me to believe that the other post was not unintentional.

More recently, here's another look at that first pole. Either more people plucked away at it, or the staples came off as more recent posters were removed.

Whatever the case, it sure breaks the monotony the street and really gives you something to think about!
