 "French fighter pilots inflicted more than half the losses suffered by the German air service in the Great War, and the French aces accounted for nearly half of those. Based on extensive research, noted French aviation historian David Méchin has documented the personal stories of these aces in the French Aviation Aces Encyclopedia with text, photos, detailed victory tables, and color profiles. Those stories are told in depth for the first time in English in this landmark series of books." - From a blurb on the book. 

These books are full of photographs both of pilots and planes. Each book has at least two hundred pages and details of at least eighteen aces in  each volume.
