The fantastic-looking 1976 book by typographer Walter Diethelm (1913-1986).
Essentially the vintage edition of Hyland & Bateman’s Symbol (thanks for the tip, Stephen). See more on this Flickr set by Unit Editions.
This last photo (below) is from a similar set by Antonio Carusone. There are apparently a few of those translucent sketch pages throughout.
I found a Flickr set of another Diethelm book, Visual Transformation (not logo-specific, but still interesting).

My favorite book. Full of imaginative and powerful icons.
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!
This reminds me of a set of books I read while I was interning. The inspiration is one of a kind.
Thank you for posting. I may have to dig out some of my old books from my Communication Design courses.
Great to scan through it.
I have David Consuegra’s En Busca Del Cuadrado, a cool one too.
