The scoreboard says 'Classement des appereils' (Classification of the planes). Data for the bottom right aircraft. Immediately to the left of that, event number 17 is a Morane-Saulnier AI/MoS 30, probably F-ABAO. F-CMAW and F-CMAY, bottom left, are Blériot-SPAD S.27 aircraft, and F-FRAA is a Potez VII. Both types were two-passenger airliners derived from warplanes, like the Breguet 14T to the right of this cropped image, F-CMAF. The F-CMA* registrations block was issued to the Compagnie des Messageries Aériennes, F-FRA* to the Compagnie Franco-Roumaine de Navigation Aérienne.
