For the moment, make a mental note of the shape of the chin. Notice how pointy and crooked it is, how the cleft is not aligned with his nose, and how weak it is on the right side (his left). This will soon become important. 
     Now, if you have any doubts about how accurate this process of facial comparison is, take a look below.   
 

                                                     

     This should quell any doubts you have about how accurate this process is and how much the skull changes with age (not at all). Even 35 years later we see an absolutely conclusive match. Except for a minor cosmetic change in the chin, (which we'll get into in a moment), there is virtually no change between these pictures taken at least 35 years apart.      
     Again, from a a scientific stadpoint, there is no doubt whatsoever that this is the same man. So now, let us take the June 1966 photo from the first page and compare it to the March 1967 Sgt. Pepper's picture from above. If my previous assertion is incorrect, and these are in fact the same man, then these pictures should match as perfectly as the pictures above...
