Thjnk is an agency based in Germany that came up with this clever campaign to bring awareness to missing children.
The billboards show Facebook pages of children that have been reported missing and are still not found. The top cover photo blends in perfectly with the background, so that it looks as though the child is standing in the middle of the street, looking around all by himself in his or her profile picture. To make it even more lifelike Thjnk made the children in the pictures move around constantly to make it appear as if they are lost.
The goal of this campaign was to make people feel more involved, instead of ignoring the fact that missing children are still out there. Hopefully the people of Germany (and elsewhere in the world), will take more action after seeing this campaign.
