The book’s arranged according to subject, and analyses the development of the sign as language. The text’s in German, French, and English, featuring work by Paul Rand, Adrian Frutiger, Lance Wyman, and many other renowned designers. It’s essentially a vintage edition of Hyland & Bateman’s Symbol.

This last photo (below) is from a similar set by Antonio Carusone. There are apparently a few of those translucent sketch pages throughout which is a lovely touch.

Thanks for the tip, Stephen.

You can see a Flickr set of another Diethelm book, Visual Transformation. Not logo-specific, still interesting.

Thanks so much for posting. Great to see the colour pages. One of the first books I was exposed to at university, sadly someone’s photocopied version.

Found in a second hand book store? What a find, I bet it’s the first thing you reach for when working on any new logos!
