As shown in the photographs. This is for a
1925 dated letter signed by British poet and printer Francis Meynell, on letterhead from The Nonesuch Press, to Harvard Press Director Harold Murdock (spelled Murdoch incorrectly) Esq. regarding a mis-write on the imprint of a book they were publishing.
After comparison with other exemplar and evaluating the various characteristics, I have zero doubt with regard to the authenticity of the item. I have 10 years of experience successfully examining important documents from estates and collections.
