In 1966 the Nul Gruppe (Armando, Jan Hendrikse, Henk Peeters, Jan Schoonhoven) proposed a major installation Zero op Zee where works by the Dutch artists would be presented along with related artists from Europe, America, and Japan. The event would take place on the Pier of Scheveningen. It was never realised.

As part of an exhibition in Amsterdam in 2012, Henk Peeters created three photo-montages based on the original plans and also a small set of cinderella stamps.

This book was poorly designed and the page block in almost all copies has fallen away because it was glued (lumbeck binding) rather than a more secure design. This example suffers from the same fate - else it is VG. Priced to reflect this.
