The Modern Forgery Hypothesis

5) Earlier provenance: The Marci letter's wax stains line up perfectly with the wax stains inside the front cover. I know the counter-argument: What about the folding pattern? 

I think most of your points are valid, but this one simply isn't true.  The line up of the stains on the cover isn't "perfect" by any standard.  But more importantly, the stains are in the wrong place on the book cover to account for the letter being their source. The distance between the stains seems to be approximately the same on both the letter and the cover, but only if you only unfold the letter, and then place it in a completely unnatural position and orientation -- with the letter itself extending beyond the cover.
