Mr. Beck’s Underground Map

I can’t find this on Amazon, Borders or Barnes and Noble. “The story of the map of the London Underground is interwoven with the life of its designer, Harry Beck. From the earliest sketches in an exercise book, to its present form, this book shows how the map evolved, was updated, constantly reshaped and reworked over the course of thirty years by the man who became obsessed with the map.” By Ken Garland.
