Situation: How do you tell an abused child how to get help if the abuser is standing nearby?

Solution: Hide the message in plain site.

In a new campaign titled Only For Children, the Aid to Children and Adolescents at Risk Foundation (ANAR) in Spain is cleverly using lenticular printing to hide a message and phone number so that only kids can see it. Lenticular printing is the technology used to create the 3D-like bookmarks you often find at bookstore check-outs.
