Original Vintage Poster on Linen by A. M. Cassandre, Bonal Gentiane-Quina, 1935

Behind the stylized curves of this chiaroscuro silhouette lies the full graphic flair of A. M. Cassandre, the undisputed master of modern advertising posters. Created in 1935 for the renowned apéritif Bonal, this bold composition blends geometry, motion, and color with striking virtuosity. The slogan “Ouvre l’appétit” (“Opens the appetite”), cleverly integrated into the shape of a monumental key, illustrates the invigorating power of this gentian and cinchona-based drink from the mountains of the Grande Chartreuse.

Printed by Alliance Graphique using the lithographic process, this large-format poster (approx. 62.8 x 46.8 inches) impresses with its strong contrasts and sunlit gradient—an iconic color signature of Cassandre's work.

Linen-backed and preserved in excellent condition (grade A-), this rare piece embodies the golden age of French poster art in the 1930s. It will appeal to discerning collectors as well as lovers of avant-garde graphic design.
