Original piece of the polished limestone from building number 5 of the New York World Trade Center. Relics from the World Trade Center buildings are extremely rare. This piece was removed before 9/11 making it one of the few remaining pieces in existence. We obtained a small amount of these from one of the building maintenance supervisors. Mounted in a Riker frame and matted with Memorial art. This makes a fitting tribute to the brave men and women who were part of this historic event. Matt color and art might vary from piece to piece. Certified by The Gettysburg Museum of History. Museum documentation included. VERY LIMITED Supply!
