I had an IDENTICAL photo, so I guess that they cannot be hand-written autographs, and must be mass-produced. It was given to my Mum and Dad in the early 1960's by Paul McCartney's auntie, who they used to see in Eric's Club in Claughton, Birkenhead.
However, I found another identical one on a South African auction website which sold for £800, so I listed mine on Ebay and I got £600! I got lots of messages saying that it was mass-produced (which is what I said in my listing) and worthless, but I guessed that things get more collectable when they have nearly all disappeared.
Luckily, I also kept most of my 60s and 70s vinyl, and some of those LPs and singles fetched between £30 - £150 on Ebay.
So, good luck with your own Beatles photo!
