The loose sheet prints a poem by Werner Duggelin. The prints are replications of letters sent by Tinguely to his patron, Maja Sacher. She was the heiress to the Hoffmann-La Roche fortune. The original letters consisted of drawings, collage, handwriting, found objects. The complete collection of drawings is reproduced in the book "Brief von Jean Tinguely an Maja Sacher" that is also held by the Sackner Archive. -- Source of annotation: Marvin or Ruth Sackner.
