At the first glance, you must have felt like the picture had really come to life. This is purely a work of creativity. If you realize, there is always a gap in every poly bag or paper bag where you slide in your fingers to hold the bag. The artist has simply used that space to depict the mouth of the woman. Thus the person who is holding it by inserting the fingers inside the gap is not even aware of the fact that from a distance it looks like the lady printed on the bag is actually eating her hand.
