I found this interesting. The billboard ad gives a different message to shorter people--children--than the adults that might be with them. The kids see a message to call in child abuse. Not usually a fan of messages designed to bypass parents to get to children, but this seems appropriate. Innovative Ad
I like the idea of this and if it helps just one child it's worth it. I just hope this type of advertising is not used to make kids pester their parents more for toys and other things.
