I want this book!
I was over at Sell! Sell! towers earlier today and saw them posting about this book, Corporate Diversity: Swiss Graphic Design and Advertising by Geigy, 1940 - 1970 published by Lars Müller and the Museum für Gestaltung Zuurich. I've posted about Geigy before here, but I've never seen this book and it's fantastic!
The work throughout is simple and striking - quite rightly the book relates Geigy's house style to other influential advertising and design of the era, for example Olivetti, and as you can see they were definitely along the same lines.
These ads were designed by Giovanna Pintori who worked at the Italian company Olivetti for 27 years!
