Les vérités sur l'utilisation de l'aviation militaire avant et pendant la guerre

First edition of this work published in Toulouse, the cradle of aeronautics.
Light worming to the boards.
Rare signed autograph inscription from Clément Ader to Ernest Cauvin: « A monsieur Ernest Cauvin membre de l'Aéro-Club. En souvenir du 2 mars remerciements et sincère hommage. » ["To Mr. Ernest Cauvin, member of the Aero-Club. In memory of March 2nd, with thanks and sincere homage."]
This dedication was most likely written on March 2, 1922, on the occasion of a banquet of honor organized by the Aéro-Club de France at the Palais d'Orsay to celebrate the presentation of the Commander's cross of the Legion of Honor to Clément Ader, the first Frenchman who, as early as 1890, made flight attempts with his prototypes named "Éole" and "Zéphyr." This final tribute marked the pinnacle of the career of this brilliant inventor, from whom the French army had nevertheless turned away after the inconclusive takeoff demonstration of his "Aquilon" at Satory in 1897.
