The image is a poster for an opera performance at the Theatre de l'Opera in Paris, France. The poster is titled "Fête du Printemps 4ème & Dernier Grand Bal Masque à l'Opéra" which translates to "Theatre of the Opera" in English. 

In the center of the poster, there is an illustration of a man and a woman dancing together. The man is wearing a top hat and a suit, and the woman is dressed in a yellow and white striped dress with a mask covering her face. They are both holding hands and appear to be in the middle of a dance move.

On the left side of the image, there are two other people, one of whom is holding a fan. The background is filled with colorful illustrations of other dancers and performers. The text on the poster reads "Jeudi 17 Mars (Mi-Creme) Fête d'un printemps, 4èème et dernier grand bal masque à la l'opera" which is French for "The grand ballet masque" in French.
