Smiling boy in green

Do you remember the cover picture of the classical U2 album "War"? It has a young boy on it who is grim about the war and the world and all the rest...

This young boy seems like the younger and more happier brother. He smiles in a pedestrian tunnel in Halle, Germany, in a world that isn't so much better than 40 years ago. But if he rules the future it seems it could be.
