"They Just Lie There, And They Die There"

I know there is lots of excellent street art throughout the cities of the world.  But there is one guy in Roma whose work I love.  Earlier this year, I admired a huge sidewalk version he'd done of the "Girl With a Pearl Earring."  I watched him last night work on his "Mona Lisa."  It's fab.  And it's right down the block on Via del Corso.  I don't know who he is (and I'll try to find out), but I like his version better than the one at the Louvre.
