For any already convinced enthusiast of America's greatest contemporary architect, this book, posthumously published, is a must. For the doubters -- and the uninitiate- it is a revelation of what a ""living architecture"" can signify. Wright was far ahead of his time; that is fully revealed in these drawings of projects, some of which go back half a century, and many of which incorporate what were then revolutionary concepts of form, building materials, structural details, and- possibly most significant of all- a unity of setting and structure. Desert and mountain backgrounds provided challenge and some of the most exciting drawings shown here belonged in those settings. The utilitarian aspects, too, will surprise many, for here are projects designed for as wide a range of needs as hotels, shops, theatres, public buildings, gasoline stations, funeral parlors, and so on. An introduction by Italy's Professor Giuseppe Samona provides an interpretation of Mr. Wright's architectural achievements and goals; A. Hyatt Mayor, of New York's Metropolitan Museum, contributes an estimate of the drawings, which are in themselves, works of art rather than mere examples of draughtsmanship. A very special sort of book which probably only the specialists and the larger public libraries can afford.
