Billboard Allows Kids to see Secret Message

A new campaign made by Spanish Organisation ANAR Foundation (Aid to Children and Adolescents at Risk) will use lenticular printing to secretly send a message to abused children without alerting their abusers. 

Anyone over the height of 4'5" will see the face of a child with no injuries and a caption that says "Sometimes, child abuse is only visible to the child suffering it". 

While anyone shorter than that will see a different version with a childs face that has been abused and a caption saying "If somebody hurts you, phone us and we'll help you".
