Number 2! A wonderful design book that has been on the most-wanted list for a while now, 'Schweizer Industrie Grafik (Graphic Design in Swiss Industry)', Hans Neuberg, 1965.
It's packed full of great typography and graphic diagrams, many of which look like they could have been designed now - not 43 years ago! These images are from Aisle One's Flickr Group where you can see a large selection of pages from the book. They do come up on Ebay every now and again, so maybe one day it will be mine!
