~~Man or Woman~~
Do you see the man or woman? Or do you see both? Or are there THREE people in this picture. If you are missing it, the man is the brown moustache. The woman is looking to the left and you can see here eye and nose protrude from the left part of the image. There is also another face - the woman's chin is the nose for this third face, and the wrinkle in the womans neck is the mouth.
Now the next time you are at your local shopping mall, and you see a person that you just aren't sure if it is a man or woman, just remember this fun drawing and as you are trying to figure it out, remember that at least it's not as ambigious as this picture is!
