This unsigned print was probably done while Roth was working as a graphic designer in 1960 at the advertising agency of Karl Gerstner and Markus Kuttner in Basel. It was part of a portfolio of 8 prints purchased from Larry Wallrich in Toronto that are not listed in Roth's major catalogues nor is the Dieter Roth Archive aware of their existence. One signed print (Galerie Stahli in Basel) + 7 unsigned prints were sold by the Sackner Archive to Zucker Art Books in 2010. The unsigned duplicate print from the series of eight has been framed and retained by the Sackner Artchive. -- Source of annotation: Marvin or Ruth Sackner.
