machine-powered aircraft

Le Royaume de l'Air, or the “Kingdom of the Air,” was published in Paris in 1909, during the first decade of machine-powered aircraft flight. It was written for young readers and includes plentiful illustrations and photographs documenting the historical development of aeronautics and contemporary innovations in this new technology. There are very few copies in libraries, and the Smithsonian is fortunate to have two in its collection. This copy is in need of extensive preservation treatment.
