First off I want to say that I am not making a political statement by posting this photo - I found it highly interesting. If you look closely (click image to enlarge) on the photo someone has sneaked in a "not" with permanent sharpie. This was found at Queen at Ossington yesterday. The art on these garages changes quite a bit and it's always interesting to see what's new. Here's a Google Street View image probably taken in the summer of 2009 and shows the garages before they were repainted:
As you can see the garage with the satellite dish is the one that currently has the Rob Ford slogan on it.
