you should put the image and lettering under higher magnification. I'm skeptical because 8x11 is a standard paper size (8.5x11) and when we see reprints (fakes) they are done on home printers and then aged. Can you get your hands on one of these cheap $15 60-100x microscopes? You'll be able to see the dot pattern if there is one.
