Jochen Gerz : salviamo la luna = save the moon

Catalog of an exhibition held in Cinisello Balsamo, Italy, 2005-2007.
At head of title: Museo fotografia contemporanea.
We cite from the cover:
"Save the Moon is a public work of art that was entirely realised in the town of Cinisello Balsamo, on the outskirts of Milan. A total of 2,734 individuals responded to the invitation of the German artist Jochen Gerz and presented themselves to have their photograph taken at the Museo di Fotografia Contemporanea. Subsequently, each participant took to the streets of Cinisello bearing an enlargement of his or her own portrait on a placard. Each person alone, at night, for at least an hour: no reason was given for this rather unusual happening. All these portraits were then gathered and placed on exhibition in the rooms of Villa Ghirlanda, where the museum is housed. At the end of the exhibition, each participant was presented with a portrait —not of themselves, but of another participant— to take home as a keepsake. In this way, the entire collection of Save the Moon, though technically the property of the museum, has entered the public domain, scattered in the homes of the participants.
This volume includes the portraits of all of the participants, the chronology, and the photographic documentation of the work."
