Official Posters For Men In Black 3 – Cross Your Eyes And A 3D Sail Boat Appears?

I'll apologise in advance for the furious headache I'm about to give you.

There's a URL on those posters – TheMenInBlackSuitsAreReal.com – which leads to a rather banal Facebook page. I'm sure something will appear there sooner or later, but I don't know what. When I do, I'll pass it on.
