Wow, that is a surprise. When I bought a box from Bostick & Sullivan not long ago, they only had two boxes left, and I got one of them. Whoever bought the final box was, apparently, an unwitting participant in history. At the time, I had the distinct impression that they fully expected to be getting more stock. Centennial POP provided my first printing and toning experiences years ago, and I'll miss it, for sure.
