The original edition [...] inspired a whole generation of grateful workers in polytope theory. Without it, it is doubtful whether many of the subsequent advances in the subject would have been made. The many seeds it sowed have since grown into healthy trees, with vigorous branches and luxuriant foliage. It is good to see it in print once again." -Peter McMullen, University College London | Convex Polytopes by Branko Grünbaum, Hardcover | Indigo Chapters
