I'm not arguing that the Obama version isn't a fake. I'm sure it is. But the proof in the video that the original was just the grandparents is very unconvincing because of the poor Photoshop work done in an attempt to regenerate the original.
Maybe you can explain why the wall and the pavement have been mutilated in the 'original' fake.
This is what the wall should look like.
Posing in Central Park, wearing the same clothes. Was he there or has he been imposed upon the background?
