You'll notice--especially--the eyes are very reminiscent of the Paul of today. Notice also the angular face, which looks much more like the face of the two photos immediately below as opposed to our Paul's distinctly rounder face that you can see in photos 3 and 4 below. I've been contending for some time that our Paul never made it to the 1966 tour and these photos lend credence to that theory.
My concentration in this blog is on Paul, but if you look at "John" in the WCFL photo you'll notice that this man---with his narrow face--is not our John. (See photos below for comparison.)
