The Friday File: An Italian artist just had an immaterial sculpture, an artwork of literally nothing, auctioned for $18,300. In February, the same artist exhibited another immaterial sculpture in Milan demarcated by a square of tape on a walkway. Since, he’s installed Afrodite Cries in NYC, demarcated by an empty white circle. How much for a suit by the esteemed weavers in Hans Christian Anderson’s The Emperor’s New Clothes?
