Raymond Savignac, often just abbreviated to "Savignac", was a French graphic artist famous for his commercial posters. He was born on November 6, 1907 in Paris, and died on October 31, 2002 in Trouville-sur-Mer (Calvados), aged 94. His work is distinguished by a humorous simplicity.
Self-taught, he started designing posters under the direction of Cassandre, but met his greatest success with the poster for Yoplait yogurt, which featured the udders of a cow directly supplying the "milk yogurt" with milk.
Another famous poster was called "La Guerre des boutons" (War of Buttons).
A permanent display of his work may be found at the Montebello Museum in Trouville, where he spent his last years. There is also a beachfront walk dedicated to him. Many of his posters depicted the Norman seaside town. These works can be seen there. His murals can be seen also around town.
