What first seizes the viewer in Dentifrices des Bénédictins de Soulac is the sheer exuberance of its central figure—a figure whose wide, gleaming smile is both the promise and the proof of the product being advertised. The character, draped in a flowing red cape and white costume, strides forward with theatrical confidence, one hand on hip and the other triumphantly raising a mirror. The mirror is no idle prop: it draws our attention to the subject’s teeth, the very focus of the poster, while the exaggerated gesture and the cascade of red fabric behind her amplify the sense of vitality and self-assurance.

The palette is bold and direct, with the stark black background pushing the figure—and the promise of perfect hygiene—directly into our space. This work, created by Leonetto Cappiello in 1922, belongs to the golden age of the advertising poster in France, a period when commercial art was at the cutting edge of visual culture. Cappiello, known for his witty, larger-than-life characters and vibrant color, revolutionized the field by giving products a personality and a story. Posters like this were commissioned by companies eager to stand out in the crowded urban landscape, and were printed in large runs to be plastered across Parisian walls.

The Bibliothèque nationale de France preserves this example, a testament to both the ambitions of early twentieth-century commerce and the enduring allure of Cappiello’s theatrical vision. One is left to wonder: does the promise of a dazzling smile ever really go out of style?
