Check out Vhils,  25-year Portuguese street artist who uses sledge hammers to create stunning wall art. “Using scalpels, hammers and pneumatic drills, Vhils now retools billboards from Berlin to Shanghai, Moscow to Rio, replacing the usual politicians, models and celebrities with the faces of “everyday heroes” that he sketches on the subway or glimpses at flea markets.” (The Independent, March 11, 2013)
