Hi,
Hey, Kilian, thanks so much for posting those marvelous old German book covers! I have
Der Flieger Thom but my copy lacks the dust jacket

The German artists of the war years, '20s and '30s had a marvelous graphic style.
Anyway, here's another in the "Hobby Helpers" series, this book on Fokkers of WWI by Peter M. Bowers. The cover is by J.D. Carrick, whose work is always first-rate.
