A Spanish organization called "Aid to Children and Adolescents at Risk" (ANAR) created a new ad campaign to bring awareness to kids at risk, using a cool new idea (but a very old technique). By using Lenticular printing, they were able to show two different ads in one print - one for kids, and one for adults. Adults see a different image and message than what the kids see. Smart, creative and important.
The 1940 technology lets you see different images/designs depending on your viewing angle. You must remember those magic lenticular rulers and pens from school that use the same idea.
When an adult (anyone 10 years old or older - or taller than 4’5″) looks at the ad, they see the image of a sad child and the text, "Sometimes, child abuse is only visible to the child suffering it." But when a child shorter than 4’5″ looks at the ad, they see the bruises on the face and also a different message, "If somebody hurts you, phone us and we’ll help you" and the foundation's phone number for them to use if needed.
