and 148 is also photoshopped?
It doesn't appear to be. You've got eyeline matching with the girl, the cast shadow behind MLK's chin seems appropriate to where a flash would originate, though the highlights are somewhat strong compared to the women but he's black and the women may be wearing foundation. That one is tougher to judge/easier to fabricate because of the blank space behind him, his shadows cast onto a white wall, theirs cast onto a dark wood panel, etc.
I'm not saying any picture with a Romney and MLK is fake. But, blindly believing everything we see, no matter how preposterous, in order to validate what we believe is beyond the pale.
