[Design of Marci Letter]

[asteckley]

The next question from someone will certainly be - can it be tested? Sure, but I guarantee you that there's no way the Library would agree to the time, expense, risk, and staff time that would be required when the outcome really wouldn't add anything to our understanding of the letter. 

Testing seems unnecessary when there’s still more to learn from non-invasive photographic imaging. If they were to deny that, then the next question from someone will certainly be: what is being protected— an artifact or a theory?
