The poster depicts a pilot scattering roses from his airplane flying high over the Nice coast.
The lettering at the top is in a distinct Art Nouveau style and surrounds a crowned red eagle, representing the arms of Nice, with exaggerated wings extending far beyond the shield and resembling the wings of an airplane.
