Found around Fourth Ave. #2

A block west of 4th Avenue, just north of 8th Street on Herbert (an alley), I spotted this painting on the back wall of a building, facing a trash bin.

Why would an artist put something this interesting in a spot where people have to track it down? I don't know... but it's one of the things that makes murals interesting to me.

Update, January 22, 2011: The mural is gone — behind one of the many new-looking rectangular patches of paint on the alley walls.
