This elegant vintage French poster promotes Saumur-Champigny, a celebrated red wine from the Loire Valley, under the poetic theme 'Harmonie.' Illustrated by Jean A. Mercier in the 1930s, it features a graceful female figure raising a glass of wine, surrounded by grapes, flowers, the Loire River, and the château skyline of Saumur. Rendered in soft, painterly colours with flowing lines, the composition evokes refinement, balance, and pleasure, making it a classic example of interwar French wine advertising and highly sought after for its romantic, Art Deco-era charm.
