The Harnessing of the Giant SquidsStreet Art // Saturday, 14 May 2011
"A liquid secreted by the mucous membranes of mammalians." That is the Wikipedia description of Phlegm, as well as the name of the artist who painted this mural in Sheffield, England. Eventually, when a significant amount of rain comes this canal will fill with water and this piece can take off in full effect.
