I introduce to you, The Holy Grail.
Massimo Vignelli has published an amazing 96 page book on better understanding typography in graphic design, according to him. The book gives specific details on Vignelli’s methodology and approach as well as how he decides on paper sizes, typefaces and other tangibles. There is also a nice section on grids.
It’s an excellent book that every designer should read. The book is available for free online in PDF format but I do hope they print this one out because it’s a masterpiece in my opinion.
