A Spanish organisation that aims to combat child abuse has designed an ad that displays different messages for adults and children. When an adult looks at the ad by the Aid to Children and Adolescents at Risk Foundation they see a picture of a healthy looking child and the message: “Sometimes, child abuse is only visible to the child suffering it.” While anyone smaller than five feet sees bruises on the child’s face and the message: “if somebody hurts you, phone us and we’ll help you”.
