Why would it have "Z2"? No one would make that kind of typo, since the "Z" and the "2" are quite far apart on the keyboard. Plus you'd have to shift to get that upper case "Z".
The fact that scan apparently distorted a "2" into a "Z" is further evidence that the apparent "2008" was and is really "2006".
it’s all the same font and the letters line up vertically between the two copies. I copy all my screen saves to PNG files now
