These next two additions to my collection have to be the most rare and the most expensive but also the most satisfying. Publicity and Graphic Design in the Chemical Industry (1967) and Graphic Design in Swiss Industry (1965) are both by Hans Neuberg and are part of the excellent ABC Verlag collection and contain page after page of some of the finest design work you’ll ever see. From packaging to letterheads these books will keep you hypnotized for hours… if you can find them.
You can see more photos from both books on my Flickr page.
