On close inspection, you'll notice that the "P", "A" and "N" are of slightly different weights, and on the 135 box the "A" appears misaligned.
Also, the style of the large letter "F", with the extra little serif sticking out to the left at the top, is not the normal appearance of the "F" in that typeface (Copperplate Gothic). It looks as if it was made from a letter "T" by moving the vertical stem and cloning one of the horizontal bars. (You can even see some signs of retouching in the interior of the letter.)
Looks to me like someone having a little image-editor fun with a Tri-X Pan Professional (ISO 320) Pro-Pack box. Dunno if it's Russ spoofing us, or someone else spoofing him, but I'm not going to be holding my breath for this one. Sorry...
