99 percent chance its secretarial even if it was obtained at that show. Almost all of the autographs obtained at the concerts were signed by Neil Aspinall (first road manager), Mal Evans (equipment and road manager) or PR man Derek Taylor

you could probaly value this yourself. first step i would take is have a look at the photo paper it is signed on, does it look old and faded ?, is it dated on the photo paper?, is the photo paper faded? is it signed in black marker or writing pen?
are the concert tickets faded? has the picture been hanging up for a long time? and of course were did they get it?
truth is authentic beatles autograhs are very rare, specialy the whole band together.
as for valuation advice every valuater is a crook, they will tell you what ever you want as long as they get the money.
or you could post it on this site (is my autograph authentic) forum and have it done for free.
it is hard to tell without seeing it.

someone on our rescue kennels forum has asked me if i know a rough value on an autograph she has , so i told her i would ask on here what you think and what advice to give her.

Its a framed photo of the Beatles, and all signed by them, as well as 2 concert tickets from the 1960's gig they did.
