A semi-famous headstone of John Laird McCaffery with a hidden message.
This photo shows the epitaph in more detail.
It is in Section C Plot #01369 of Montreal's Notre-Dame-des-Neiges Cemetery. @ 45.498725, -73.604483 see map -->
Note: The actual location is a bit further East of the point shown on the map. It is only one or two rows in from the road.
Here's a clearer but non geo-tagged picture. If you want a similarly well lit picture go before noon as the photo is looking towards the West.
