The art world swarms into Venice distributing itself in every hotel room and every possible exhibition space. Large art works pop up over night, a wafer thin Austrian house here, a billboard image of the Virgin Mary that looks like it’s been made out of bottle tops there. But underneath it all the regular art business of Venice ticks on untouched. You want a statue of Michael Jackson cutting off Ronald McDonald’s head? It’s waiting for you in a dealer gallery somewhere near St Mark’s Square.
