This picture is from a June 2008 edition of Newsweek magazine. It appears to be Obama reaching for the "Presidential Seal". Please take a close look at the ring on Obama's right hand.
Obama is wearing a masonic ring. The square and the compass are clearly visable.
The important thing to remember is that these pictures are carefully staged. I'm sure they (Newsweek photographers) take several pictures. The ones they publish are obviously the ones they want you to see. This was either done for your benefit, the general public, or for the benefit of other freemasons, probably both. Either way the message is clear. Obama is a freemason and another freemason is going to be President of the United States.
Here are a couple of close-ups of Obama's masonic ring.
