Post a message on Herman Darvick's profile asking him to comment. Also Andreas Weimer's.
Will do, thanks!
I think you're right, James, but I personally wouldn't want someone to rely on my opinion of the authenticity of Kennedy's autograph. We have a number of members who are are quite good at Kennedy, but because Autograph Live doesn't get that much historic activity, we don't see them as much as we could.
Herman is very good on American historic autographs especially. Andres Weimer is as well, and JFK is a specialty of his. He's written more than one signature study on Kennedy.
Either one will give Adam a reliable opinion.
If you've been seriously studying JFK, then your opinion has real validity.
the signature and postscript is authentic. A form letter, given to a lot of people with the same content, I remember a dozen like this, but all signed personally by JFK, some with a postscript.
