This is WARPLANES OF THE LUFTWAFFE and AMERICAN WARPLANES OF WORLD WAR II. They are large hardcover books, approximately 31cm tall, 24cm wide, and 3cm thick, weighing about 1.5kg each. They are large format with many photos, making them very interesting to look at. [Please also read] The book on the German Air Force has a tear on a part of the cover, as shown in the last photo, but the inside is clean. They have been stored in a bookshelf with doors, but please understand that they are old books before purchasing.
