Billboard Shows Different Messages for Kids and Adults

A billboard in Spain created by an organization dedicated to aiding abused children shows a different message to children and adults, even if both see the ad at the same time.

The feat is achieved by use of lenticular printing, which allows different images to be seen depending on the vantage point. In this case, if the billboard is seen by children under 1.3 meters (about 4 feet 3 inches), then the message, "If somebody hurts you, phone us and we'll help you" appears along with a phone number for the ANAR Foundation (Aid to Children and Adolescents at Risk). There's also a message just for adults, a warning saying, "Sometimes child abuse is only visible to the child suffering it."

The idea, as ad agency Grey explains, is that abuse victims might see the message as they're walking down the street with their abusers.
