The Hermitage 

This Art Nouveau poster, designed by Czech artist Alphonse Mucha, features a woman with flowing red hair, adorned with lilies and a jeweled headband. The poster is an advertisement for the Parisian magazine "L'Ermitage," a publication for the theater and fine arts. The poster exemplifies Mucha's signature style, which is characterized by its decorative elements, stylized figures, and use of vibrant colors. He is best known for his designs for theater posters, particularly for Sarah Bernhardt, and his work is considered a key example of the Art Nouveau movement.
