This book documents Bertozzi's trip to Buenes Aires, Argentina, and New York and New Orleans, USA with text and photographs. The latter were the basis for the exhibition. According to Bertozzi, "an Inist photograph is the uncontaminated result of a creative operation realized exclusively by the insertion of a film in a camera. It is therefore a form of Inist writing obtained with light and without manual intervention, or the computer or any other means. -- Source of annotation: Marvin or Ruth Sackner.
