'Only For Children' is a unique billboard in Europe that was specifically designed to help kids report abuse, even if their abuser is standing right next to them.

The sign was designed by Grey Spain with a hidden message that only kids are able to see.  The message displayed to kids reads:

If somebody hurts you, phone us and we'll help you

A number to an anonymous call center is also included in the message that kids can call to report abuse.

The number of child abuse cases reported every year are staggering, but most people think that they pale in comparison to the amount of abuse that goes unreported.  This sign won't fix the problem of abuse, but it might help kids realize that they have a voice.
