About his World Trade Center pictures Paul says: “Growing up, my father had a blowup of the New York City skyline he shot in the 1940’s or early 50’s on the living room wall. That world was gone by the time I started shooting and now my images also depict a world that no longer exists. The reasons are different, but the skyline is always changing. I like history, especially photographic history, and these pictures are my contribution."
