Thanks for posting that...I'm no expert, but there does seem to be something wierd about grandpa's left arm and hand. Seems like the arm is straight down (by the look of the shoulder)...he must have a really long arm to get the hand up like that. Maybe it's an optical illusion.
It was always the women, and above all the young ones, who were the most bigoted adherents of the Party, the swallowers of slogans, the amateur spies and nosers−out of unorthodoxy
All I can say is what I said about the birth certificate: if they were going to fake something and release it to the entire world, do you think they would have photoshopped in a hand to make it look weird or left something important off the BC?
Since the hand is in the air over Obama's shoulder it appears it was in motion as the grandfather was about to place it on Obama's shoulder.
But the bigger question is: why would they even have to resort to photoshopping it? They are his grandparents, after all and there are other photos of the three of them together.
