Historical NotesLucas Berstein and Erica Feinstein, elementary school classmates in Pennsylvania, assembled this collage of nearly 3,000 distinctive U.S. and international postage stamps, one to memorialize each victim of the attacks. A thin plastic film bearing the names of victims overlays the stamps. For several years, the collage was exhibited at Berstein and Feinstein’s school. Berstein’s uncle,
Morton H. Frank, was killed on 9/11 while working for Cantor Fitzgerald on the 104th floor of the North Tower.
