The Modern Forgery Hypothesis

[ReneZ]

if we find no other examples of the same "three tasseled hat" watermark in the other (known genuine) papers of Marci, even though we cannot see every scrape of paper of his, nor the imagined "scribe" (previously used to explain observed problems with the 1665/66 letter), it is still evidence that that letter maybe inauthentic.

Patently incorrect.
