This collection consists of a circa 1926 French-language booklet (11 x 8.5 inches, 28 pages) written by Victor Cambon entitled La Ligne Aérienne France-Afrique-Amérique du Sud (The France-Africa-South America Airline) and possibly intended to be an investment prospectus for Lignes Aériennes Latécoère. The cover features a color illustration of a stylized Latécoère LAT 15 airliner in flight over a partial globe marked with a postal route linking several cities in France, Africa, and South America. The first part of the publication provides an introduction detailing the amount of time it took for mail delivery between France and South America via ship as of 1925 and how that time would be greatly reduced if Pierre-Georges Latécoère's ideas of a France-Africa-South America air route were to be put into action. A map detailing the route and distances between France and Buenos Aires, Argentina is included; a dotted line indicates a special ship route connecting the Cape Verde islands and the islands of Fernando de Noronha off the coast of Brazil. The author provides a history of Latécoère's successful France-Morocco air mail route (started September 1, 1919, between Toulouse and Casablanca via Spain) and France-Dakar route (started June 1, 1925, to continue service on to Dakar, Senegal) as proof of the commercial viability of the concept. A section on the technical organization of Lignes Aériennes Latécoère provides information on the routes, aircraft, engines, repair facilities and procedures then in use by the manufacturer and its airline, and features several photographs of Latécoère aircraft including the LAT 15, LAT 17, and LAT 21; views of the airfield at Toulouse, France; and photographs of noted passengers on the France to Morocco route (Ligne Aérienne France-Maroc) including King Albert I of Belgium, French politicians Laurent Eynac and Paul Painlevé, Marshal Philippe Pétain and Marshal Hubert Lyautey. The second part provides more detailed information on the proposed France-Africa-South America air route, with references to test flights made over the South American portion of the route. The publication includes numerous aerial photographs of locations along the air portion of the route: Toulouse and Carcassonne, France; Barcelona, Alicante, Granada, Peñíscola, and Málaga, Spain; Gibraltar; Tangier, Rabat, and Casablanca, Morocco; Dakar, Senegal; Recife (Pernambuco), Bahia, São Paulo, Porto Alegre, Pelotas, and Rio de Janeiro, Brazil; Montevideo, Uruguay; and Buenos Aires, Argentina. The publication also contains a heavily retouched black and white aerial print photograph of Carcassonne, France, circa early to mid-1920s.
