A London dealer has this for sale at £6,750.
The dealer doesn't know the date but presumes it is later than the image it is matted with. The dealer says that the shape of the "P" in Paul suggests 64-65.
I wouldn't dream of spending £6,750 on a signed album page except under very exceptional circumstances (e.g. the Beatles making references to a gig in my home town) but I'd be interested in any views re the date. I'm pretty sure it's genuine.

I also attach a jpg as the album page image is not particularly large.
P.S. I made some minor amendments to this entry after posting it.
