This book is the catalogue for the retrospective exhibition for Schippers in the Centraal Museum, Spring 1997. It includes documentary material of his Fluxus works, publications, radio shows and performances. Overlaping texts were printed in red (Flemish) and green (English) such that the opposite colored acetate sheet must be placed over the text in order for the selected language to be solely rendered visible. The envelope contains small paper reproductions of Schippers' works from the book. The presentation of text and images in this book that depend upon superimposition of colored acetate sheets is uncommon - this is the only book in the Archive so produced. -- Source of annotation: Marvin or Ruth Sackner.
