There are several objects in this box which is like a one person "Assembling." One is an empty plastic bag with a three pages of documentation stapled to it. Gerz relates that he sent such empty plastic bags to friends, strangers from the Paris phone book and exhibition visitors at international art galleries. They were instructed to place personal old relics in the bags. Three hundred filled plastic bags were returned and sealed by Gerz who then deposited them in the construction foundation of the new Montparnasse Tower in Paris which was then covered by concrete. Since the bags were inaccessible, and no material trace of them remained, Gerz wrote that "from the idea and diverse initiatives which their realization made necessary as well as the impressions which I received during this time, I retain a memory more and more contradictory. The consequences which arise from this each day seem by now more important than the idea itself." There are duplicate, printed plastic envelopes in the box which contain black alphabet pasta and are printed with a German text. Photographs of these envelopes are reproduced in the book, Annoncenteil. The soft cover book proposes a process of photographing the second day of every month at a designated time, with a description of the location. Only two pages are complete. The printed sheet is a page from the Paris phone book. The identical labels read "Achtung Kunst Korrumpiert."
