The cannon above is set up in the front yard of a house in Wallers, a small community in northern France. There is not just a canon, if you look closely at the image, you will also see a rocket on the left, a creation inspired by Hergé's comic strip Objective Moon.
So the canon has nothing warlike, because in the same front garden there is also a peaceful mill, while in front of the farm next to the house, there is a locomotive, unaware of any harm.
