This book includes two offset prints by Peter Roehr and Herman de Vries as well as other multiples by less known artists. The exhibition was organized by Peter Roehr and Paul Maenz. Each copy is unique as each is printed on a different sheet of commercially designed, rubberized plastic. Karl Lueg who contributed to this exhibition later changed his name to Karl Fischer and became an art dealer. -- Source of annotation: Marvin or Ruth Sackner.
