Someone put a rectangle over his ear; ears have a unique pattern, and this rectangle messes with that.
Makes it hard to determine who is the double and would isn’t.
It’s more than just the ear. If you click on the larger version, and you have a sharp eye, you can actually follow the outline of the face that was superimposed. It’s a really sh*tty photoshop job. I’m astounded that they thought no one would notice.
