It’s his hand imo, the ring is visible, the problem appears to be that it is too large to be natural. How would that come about? Probably because they needed to place a hand where is wasn’t. It depends on the image they had to play with originally. If his hand wasn’t available in that particular place, they had to add it. Is that garbled? Sorry, the entire scenario is garbage.
I think they had images of him on his own in Central Park, and simply added him to the photo of Stanley Armour and Madelyn on a different occasion.
The question is why?
It would seem that the realtionship between the Dunhams and zero had broken down by this time. The fake photograph leads us to believe it hadn’t. Nothing is done without a reason.
Just funin’ ;-{)
