Foto de stock - Picture of graffitti critical of documenta seenon a wall of the National Museum for Contemporary Art in Athens, taken on 10 May 2017. This is the first time that the documenta event will take place not just in Kassel, Germany, but also in Athens. In Athens, however, the event is not being greeted exclusively with enthusiasm. Many accuse it - sometimes with graffitti - of commercialising art. In this case the anonymous spray painters - who call themselves ""The Unpolite 18"" - ask what the documenta is. The answers include: the World Fair, the Eurogroup, Eurovision and all of the above. Photo: Alexia Angelopoulou/dpa | usage worldwide. - Athens/Germany
