Sopwith Camel Aces of World War 1 (Aircraft of the Aces)
With Fokker Dr I Aces of World War I and Fokker D.Vii Aces of World War I (Part One):"The prolific Norman Franks is the author of all three of these books, though he shares the credit with color expert Greg Van Wyngarden for the two German tomes. Franks is a highly regarded aviation historian, and Van Wyngarden is recognized as one of the top authorities on World War I aviation markings, so you can bet that what you see is a fair representation of historical hues. I recommend these books, and you will find the entire series to be worthwhile additions to your library." -Mike Corr, Aerodrome
