Model aeroplanes and their engines; a practical book for beginners
A 1917 hobbyist manual by George Anthony Cavanagh, published in New York by Moffat, Yard & Company, teaching beginners to build and power model aeroplanes. Halftone photographs show frail stick-and-tissue monoplanes and biplanes resting on grass or cloth, casting long shadows, alongside rubber-band and propeller details useful as coarse-screened silhouettes, diagram sources, or period aviation texture.
