"Valmy and Lea (Cancan Café-Concert Performance)" by Jean Béraud captures the lively and energetic atmosphere of a café-concert performance in late 19th-century Paris. The painting showcases Valmy and Lea, two famous cancan dancers of the era, performing their spirited routine on stage. Their vibrant movements, with skirts swirling and legs kicking high, epitomize the exuberance of the cancan dance, which was a popular form of entertainment during the Belle Époque.
