Modell eines lenkbaren Luftschiffes. Stiff card covers, 8pp, German text. Inside back cover has a folded color drawing of a ca. 1900 Zeppelin that folds several times revealing the gas bags and interior details. Numbers on the model correspond to the facing page with a glossary of the airship components. Pages are loose from cover but color illus is very good and intact. A most unusual and scarce early Zeppelin piece.
