THRIFT STORE FIND BEATLES POSTER - IS IT A FAKE?

I found this at a little Haitian thrift store I happened to notice while driving home. When I first saw it rolled & and looking brand new I felt like I was at the World Cup & my team had just scored - all I heard inside my head was GOOOOAAAAL!!

But when I looked it over I saw it was made of copies of publicity photos (see signature on bottom of one), and their are no maker's name or marks anywhere; especially along the bottom edge.

Now I've never seen this design before so maybe it is real - can anyone tell me?

If it is a knock off or handmade does it have any value?

Thanks, I appreciate any help.

 

Did you do a Google Images search for comparables? In case you don't know, would likely date to 1969 which is when John Lennon appeared in the film below.

There are a number for sale on ebay, all unused/new condition.

 

I have never dragged a photo into google image search and got something similar out - I don't know why.
I appreciate the help - at least I can list it without worrying that I'm selling a knock off.
Thanks guys - and sorry for the trouble on such a easy one (I should have tried googling 'Beatles with British flag background poster')
