A pleasant surprise.
The approaches to design that are explored in this book can only be expected from someone intimate with the Swiss school of design thought. Willi Kunz teaches designers to be deliberate and purposeful, which will keep anybody in good stead come economic boom or bust. He is thorough in explaining visually, fundamental theories not only for typography, but for graphic design in general.
On my shelf, this book sits beside Josef Muller-Brockmann's "Grid System in Graphic Design", Armin Hofmann's "Graphic Design Manual" and Robert Bringhurst's "Elements of Typographic Style".
A definite keeper.
