Graffiti Problem?

So Montreal seems to have a graffiti problem. There is even talk about introducing municipal legislation that would prevent anyone under 18 from purchasing spray paint. But some of the graffiti is very nice. I'll post some pictures later. But for now, let me tell you about the photo. I was walking down Avenue Des Pins and I saw the work crew putting up the wooden fence in the picture. I took this picture three days later.
