I seem to recall it was a small kodak info sheet that was put out in response to photographers freaking out that Kodak was discontinuing Panatomic-X. Kodak's response that Tmax 100 was the 'replacement' didn't go over very well at all, especially since in those early Tmax days lots of photographers were having a few adjustment challenges. I will look, I may still have that printed info sheet in an old notebook.
