Here is my authentic beatles signed album page by all 4! Fortunately I was able to get this at a lower price due to ultraviolet light damage. This is an attest to blue ink lasts longer than black. Especially when exposed to uv. I will post an actual scan of the album page when I take it out of the matted frame.
Here are a few images that came with the piece. These were signed on 9/2/64 in Philadelphia. The person who obtained this was a Philadelphia policeman. His daughter sold this to Al at least 15 + years ago. This was originally sold 15 years ago as well.
I saw this Beatles Page and I Have often wondered if it was signed at the same show my set came from. The black pen again has really faded and it has one signature in blue ink. Hmmmm
