VON / BY ARTHUR ADDI KOPCKE. 1969. “FRIETAG 11 JULI”

Stuttgart: Galerie der Edition Hansjorg Mayer, 1969
30 x 21cm, 12pp. Stapled left. Each with an unique collaged page from a calendar (this one being Freitag 11 Juli) tipped on the front page. Inside is a space for the name and address of the participant on each page and a large space to add to the book in any way one wanted. On the front the text in German and English says “you are only contributing, when you continue this piece, this principle otherwise, are you only a peeper.” (sic). Each book was hence unique. VG+ example.
