Blu -Art on the Wall

The Italian street artist Blu paints graffiti on Israel's separation barrier on December 5, 2007.

Blu is the pseudonym of an Italian artist who conceals his real identity. His art is almost always political as seen here in a painting on the wall that surrounds Bethlehem.  Stumps of trees carry multiple associations including the destroyed orchards and grove of olive trees -- the livelihood for many Palestinian farmers -- that were destroyed when the wall separated the growers from their trees.
