Wall Portrait By Vhils

Vhils, a London-based street artist, created this crazy portrait on a brick wall by painting and etching layers.  It's quite intriguing.  He has so much amazing work, but this etched wall, located in London, is one of my faves.  I've done some small-scale etchings of my own (on PAPER), but I could only imagine how much work was put into this large-scale brick wall.  It's pretty awesome.
