BRANZI, Andrea ed. 
Decorattivo 1976 & 1977 (Issue 1 & 2). 
First edition. 2 volumes (128pp each). Colour plates throughout. Hardcover illustrated boards. Italian and English texts. Milan: Centro Montefibre, 1976 & 1977. 
Small peel to the spine of volume 1. Very good copies. 

An incredible pattern resource produced by Il Centro Design Montefibre, an institute founded by Andrea Branzi to research textiles, fibres and colours. 
A beautiful production that ran to just two issues. Decorattivo 1 was themed around space objects and spontaneous processes with volume 2 focusing on lines and squares. Illustrations with extensive texts capture a huge breadth of references from natural forms and landscapes, to architectural and industrial forms, to textiles and weaving methods. These copies are privately published versions issued a year before the published copies and were only available by subscription.
