To see the comparison I tried to log on to the 1956 photo. My browser said it found the site but I was forbidden to view it.
This may be only a problem for me but if there is a no entry block to the site whose address you give, then no one will be able to make the comparison.
Gay, same reaction for me. When I looked at the contact sheet, I thought, meh, let's just try it. But the guy looking back really works with the other lines of sight.
