I don't see anything wrong with his hand. But my very first impression of that photo when I saw it a few days ago was that Biden was shopped-in. I could not really determine why, just that it looked 'off.' Convinced myself it was just weird lighting until someone else pointed out why do the Carters look so small?
Now extremely aged people to shrink a bit, and I've been around nursing homes a time or two to know that they really almost start to look like children, esp. when sitting in a fluffy chair. Still….it feels off. IDK if it is the color of his suit, or the fact that both Joe and Jill seem too large in the same proportion. You might expect Jill to look larger since she is closer.
The more I look at it, the more it seems like Jill and Joe posed and were shopped into that photo of the Carters. Maybe they are in two different locations, or maybe the Carters are dead, etc.
