As one can see from the pictured Fokker Eindecker, this ad is an early one indeed.

The Zenith Vergaser (carburetor) features a marauding Zeppelin high over London.

This issue features Hermann Goering making friends with his fellow Luftwaffe airmen during the closing days of the Battle of Britain.  Der Sportflieger of that era of course contains a healthy dose of propaganda (hey, what wartime aviation magazine didn’t?), but it also contains outstanding information.

Two great pieces of artwork.  The first is from Bayerische Flugzeugwerke in Augsburg.  This is part of a several page promotional booklet, hence the German and French.  The other is cover art from Flug-Woche magazin featuring the Junkers G-31.
