Message on a Pole

I did a double-take when I passed this utility pole a block from my home last week (hit your browser's refresh button to re-run the photo sequence).

Photo taken on North Prospect Street, in Burlington, Vermont. I have no idea who put this worn and faded poster on the pole, or why. Is this graffiti, public art, or something else?

But seeing this poster did get me thinking about how we "communicate" with each other in our neighborhoods -- and how that's changing. More on this in my next post.
