It's not "art" but it's very thought provoking. My father went back to Europe and a few of his battle grounds many years after fighting in WW2. I think to try to get some sense of perspective on a place that had such a profound emotional effect on him when he was there as a 24 years old soldier.
These photographs can illustrate the horror that humans can project upon each other and when looked at later, are nothing but mundane streets, fields or buildings.
I think the concept is very powerful and extremely interesting.
