Color lithograph, 350x570 mm. The promotional posters designed by Lucien Boucher illustrating Air France's numerous air routes were famous. Here they are depicted in a splendid blue world enriched with scenes illustrating, in Boucher's typical graphic style, exploration and discovery on various continents, with the new routes to the east towards Japan and to the west towards the Americas represented by a red line. These plates are part of the rarest series in small format. Lucien Boucher (1889-1971), a famous French illustrator, achieved maximum notoriety by designing a series of promotional posters for Air France, after starting his career as a cartoonist and then as a poster designer for the cinema and advertising industry.
