I have just got more information that this autograph was obtained from seller's mother at Saint Paul - France in 1969. The autograph inscription is "John Lennon Pour Susanne". Do you think the story is possible and What will be suitable price for this autograph?
Thanks for your opinion, James. I have checked on Google and found that John & Yoko visited France at that time. Below is another autograph that he signed in 1969, which is quite similar to this one (especially "P" word).
