Aw, c'mon.You cannot really believe that. That, after a month of having them proudly posted (FactCheck made a really big deal about posting the big pictures), they suddenly pull off all of them and swap them for ones 1/10th the size??
It's like going in to buy a 20oz bottle of Coke, and all they have are 2oz bottles because they want to save money.
