When constructed at the turn of the century the Flatiron Building was the tallest building in all of New York City, towering over its neighbors. An unusual building lot, bounded by Broadway, Fifth Avenue, and 23rd Street, gave the building its distinctive triangular shape, and Daniel Burnham's architecture imbued the structure with a classical dignity that is both disarming and unforgettable. This handsome photographic essay includes over 100 images of the structure, taken by such masters as Alfred Stieglitz and Joel Meyerowitz, over a 90-year period. Quotations from historical and literary sources provide insights on how the building became an architectural icon. Some of the photographs seem somewhat repetitive, and although it is the building's exterior that is most memorable, one wishes for at least several views of the interior. These, however, are minor quibbles with what is a most remarkable book.-- H. Ward Jandl, National Park Svce., Washington, D.C.
