The paper was supposedly signed in late 1963. Paul has added the salutation “All The Best”. Did Paul sign with that salutation as early as 1963? Any thoughts on this set?
In my opinion this looks an excellent example of their handwriting. The All the Best may have been for a male obtainer since they didn't write "love" if the one asking was male. I would put the date as summer 1963 rather than late 1963 as the long low tale on the P was characteristic of his summer signings (for example in the Channel Islands).
