If you've seen the article to which *I* am referring, then you have missed the salient proof contained in it. The "t" is so distinctly different in it's several iterations, that it simply cannot be argued to have come from the same typewriter. No conceivable distortion of ribbon, paper, or any other conceivable typewriter mishap can account for the distinct difference in shape between one of the "t"s and another.
I am having difficulty finding the article, if you know where it is, do you have a link?
