This is a large-format book covering WW I’s aircraft and air services. It measures 12 3/4″ x 10.” It is also quite hefty, weighing 4 lbs and 13 ounces. [Extra shipping in the U. S. will be necessary. For this reason, we strongly suggest that ONLY U.S. collectors buy the book due to the high cost of international shipping]. The book contains more than 300 pages and more than 1,000 illustrations. The book is comprehensive. It includes aircraft from the primary combatants of WW I (France, Germany, Great Britain, Austria-Hungary, Turkey, Russia, and the U.S.), and many other nations. When I first looked through the book, I was surprised to see sections on Argentina, Chile, China, Japan, Mexico, Siam, etc! It has tons of information about virtually every airplane that flew during the Great War. The dust cover is in place. This book is ready to reveal a treasure trove of information to you.
