Book excerpt: The individuals who transformed American cities and towns in the post-Civil War decades built their homes, with few exceptions, on America's grand avenues, such as New York's Fifth Avenue and Los Angeles's Wilshire Boulevard. This book offers essays on twelve eminent urban residential avenues, each contributed by a different scholar and accompanied by twenty to thirty duotone photographs. Originally published as the catalog for the exhibit at the Octagon Museum of the American Architectural Foundation.
