1/75. Edition and signature in felt-tip pen lower right. On the back, Studio Object stamp, Milan. Publisher: Lebeer-Hossmann, Brussels, Belgium and Hamburg, Germany. Printer: Jacques Ledoux, Brussels.
The work presented comes from a Deluxe edition including a complete edition of 75 copies + 10 H.C. of the folder "Proposal, 1967-1974" which contains detailed plans of sixty-two installations, most of which have not been completed.
The lithographs were chronologically divided into four periods which corresponded to the same number of tube-shaped plastic containers in which they were contained.
These chronological groupings are also color-coded: blue line for 1967 (ten projects), sepia line for 1967-68 (fourteen projects), black line for 1968-71 (thirteen projects), and red line for 1971-74 (twenty- five projects).
The projects in their details allow us to understand how Oppenheim conceived the installations, before the shape of the space, the unavailability of materials and other circumstantial factors modified their realization and, in the same way, to imagine how new works could be created.
There is also a normal edition of 500 copies signed and numbered in pencil.
