A Spanish charity has revealed a unique poster that only reveals an anti-abuse helpline to children…or very short adults. The Anar foundation poster can only be fully seen when looked at from a child’s vantage point due to a special lenticular printing technique. When a child sees it, they see the message ‘If somebody hurts you, phone us and we’ll help you,’ whilst an adult simply sees an image of a frightened child.
