This is a wonderful, large & colorful volume full of interesting and often unusual photos. There are pictures and text of everything about the fair from the greatest, most popular exhibits and events to the smallest details. Included are color photos of posters, collectibles, toys, souvenirs, postcards & etc. Trylon & Perisphere is an authoritative and definitive book recommended for anyone with an interest in the subject matter of the 1939/40 world's fair. If you can find a copy, let me know; I would love to own it myself! Thank you for this great work.
