Most people who see the picture for the first time do not notice that it is actually both: a woman on the left who kisses a man on the right. Once the viewer discerns two individual faces, his or her brain will ‘flip’ between two possible interpretations of the mask. This optical illusion was presented to the public by the authors of this book at the 2011 Best Illusion of the Year Contest held at Philharmonic Center for the Arts in Naples, Florida.
