A vivid celestial chart produced as an Air France poster

A double-hemisphere celestial map with the constellations of the zodiac in gold and the others in turquoise, set against a sky of navy blue, both with the major stars marked. At the bottom is a globe with Air France's routes radiating from Paris and two aeroplanes circling. In the upper cusp is a hippocampus (a winged horse with a fish's tail), a logo used by the airline since 1933. In the four corners are winged wind-heads. Lucien Boucher (1889-1971), known as 'Monsieur Planisphere' because of his witty maps, produced posters for Air France nearly thirty years. This is a fine example of his work, portraying his adept use of colour.
