Norman Franks is one of the world's leading authorities on World War I fighter aviation, having published some of the seminal works on the subject. He is currently working on a long list of volumes on Great War aces for Osprey's Aircraft of the Aces series. Greg VanWyngarden has had a lifelong interest in World War I aviation, and has been particularly active in deciphering the colours and markings that decorated the various German fighters flown by the leading aces. This is his third book for Osprey, having co-authored Aircraft of the Aces 40: 'Fokker Dr I Aces of World War I' (2001) and Aircraft of the Aces 53: 'Fokker D Aces of World War I: Pt I' (2002) with Norman Franks. Berkshire-based Harry Dempsey is a talented profile artist who specialises in fighter aircraft of World War I. He has illustrated all of Osprey's World War I Aircraft of the Aces titles to date.
