We are sure you assumed it to be a close-up of a woman's cleavage. But if only your dirty mind would have focused more on the safety pin at the top, probably you would have thought in some other direction. Just look at the four corners and you will realize that it is merely a paper. It has been torn at the bottom and the fold is creating a shadow that is actually creating an illusion making you perceive it as a close up of cleavage. If you liked this illusion, do share among your friends.
