Each summer for the past several years there is a photo exhibit that runs along McGill College in Montreal. At one time it was a few blocks long. Now it is limited to just this block. This year's photos are from the collection of the McCord Museum. Each features a detail of a large photograph (which can also be seen). With photos on glass, the image could be greatly enlarged to reveal details that might not have been observed when looking at the photo as a whole. Interesting concept and well worth exploring.
