The Anar Foundation A message only for children
A Spanish charity has revealed a unique poster that only reveals an anti-abuse helpline to children.
The Anar foundation poster can only be fully seen when looked at from a child's point of view due to a lenticular printing technique more often seen in novelty postcards.
When an child sees it, they see the message 'If somebody hurts you, phone us and we'll help you,' while an adult simply sees an image of a frightened child.
