Anthony S.I kinda hate to bring this up, but I am curious, which always trumps hate for me.
If the Niagara Baking back stamp increases the value of what would otherwise be an E101 by a factor of 10 to 20 or Lord knows how much, what's to keep an enterprising but felonious graphic designer --- think Marketkingman, but with ingenuity and talent --- from attaining access to one legitimate specimen (that's obviously the tough part) and then creating an identical stamp? Obviously forgers know about old inks and grading companies see so few of these cards.
edited to add: curious doesn't really always trump hate for me. don't cross me. and don't call me Francis.
