Yet even in less explicit future works, Balthus would continue to paint pubescent girls, indeed it is for these that he is best known, with questionably prurient interest.
A retrospective exhibit of his work was mounted at the Musée des Arts Décoratifs in Paris in 1911.
After Salis opened Le Chat Noir in 1881, Willette contributed several decorations for the cabaret, including the entrance sign, a black cat sitting on a silver crescent moon (Musée Carnavalet, Paris) and the painting Parce Domine (Save us, God, 1884, Musée de Montmartre, Paris.
The painting ws done in a charming style that was later compared to that of Jean-Antoine Watteau (1684-1721).
He ended his association with Salis and the Chat Noir around 1889, perhaps due to a dispute over pay.
Always politically active, Willette unsuccessfully ran for a position on the legislative council for Paris’s ninth arrondissement in 1889 on an anti-Semitic platform, promoting himself with a strident poster.
