This season's Mad Men poster poses all kinds of questions: Whose hand is Don holding? And why is he walking in the opposite direction from the other Don holding the briefcase? Against one way traffic, no less? And, what's up with those three cops? Is that why Don in the dark suit is looking over his shoulder, all paranoid-like? Is assuming a dead man's identity criminal enough to warrant three arms of the law? Or, or would it be three pairs of arms of the law?
