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.

Cheers, Richard
