Emmett Williams & Robert Filliou.ROSAROTEN OHRENPFROPPEN.Paris: Self-Published, 1963. Single sheet,silk-screened. Near fine, but for quite faint creasing. Well preserved scarce Fluxus relic.  Fondazione Bonotto describes this sheet as a performance announcementfor "Galerie Raymond Cordier, Paris5 June 1963and Workshop de la Libre Expression, Centre Americain des Artistes, Paris30 May 196"however, I think this is actually an announcement for the 1964 performance that took place as part of "Actions, Agit-Prop, De-Collage, Happenings, Events, l'Autrisme, Art Totale, Re-Fluxus" in Aachen, Technische Hochschule.The list of performances on Williams' website (http://www.emmett-williams.com/biography/performances.html) lists ROSAROTEN OHRENPFROPPEN as performed at the Technische Hochschule,not at Galerie Raymond Cordier or Workshop de la Libre Expression.According to Google Translate:"Emmet Williams and Robert Filliou, Co-Inventors of the Spaghetti-Sandwich +,offeryourPINK EARPLUGS ++in the rooms of the TH for the price of 1 DMfor sale.Contact the inventors personally!"
