In 2011-2013, SRP was operating out of a 100-year old farmhouse in Colden, NY.
At one point, I was replacing clapboards on an outer wall, and the insulating/wind protecting paper the old builders used under them was exposed.
I photographed it two years before working on Michelle's cover. Obviously, her title led me to go back looking for interesting wall pictures. We chose this one partly because of the way the humped-up paper makes a shadow there at the bottom. And we both liked the dark stains.
