The book has fantastic photographs, both color and black and white, of the most interesting American worlds fair. The chapters are divided by sections of the fair, such as foriegn participation, transportation, communications. Some of the chapters are reproductions from contemporary sources, including the New York Times. My favorite chapter is the one showing memorabilia- a real treasure for the worlds fair collectors! The photographs are wonderful, showing interiors and exteriors, day and night shots, candids and official photos, color and black/white. The photographs are worth the price of the book, but it is well written, informative and interesting.For anyone interested in the 1939 New York Worlds Fair, this is the best!
