I agree. In the photo without Obama, look carefully at the bush above his Grandmothers left shoulder and you will see the repeating pattern. Also, look at the dark line between Grandpa's lapel and Grandma's right arm. I can't explain that phantom hand in the pic with Obama though. I think that both pictures are faked.
It is. The only photo that was released was the photo of the three of them. The one of the two of them was Photoshopped to show what the original photo probably looked like, not that it was the original photo. I remember seeing the web page of the guy that did it at the time. He clearly stated this is what it probably looked like. Both photos have been out for so long people assume they were two separate released photos and the one of the two of them was "discovered" as the original.
