this piece, "Love Unites", by Shephard Fairey is one of my favorites. Shephard Fairey is an artist [or graphic artist, whatever floats your boat] who's known for doing political art and stenciling. FUN FACT: he's also DJs by the name DJ Diabetic and Emcee Insulin! His famous print "Obey Giant" has been made into short documentary film ["Andre the Giant has a Posse"] and into a clothing line. His latest famous piece the Obama "HOPE" poster has been on the cover of Times Magazine and put into the US National Portrait Gallery.
