caption: The image shows a poster on the wall of a building depicting a group of people and a skeleton, with the text "Purifiez l'air en brulant du papier d'armenie" written across the top. The people in the poster appear to be in a state of distress, with some of them looking up in fear and others looking down in confusion. The skeleton is standing in the center of the poster, with its arms outstretched and its head bowed, as if it is trying to figure out how to purify the air. The text is written in a bold font, emphasizing the importance of the message.
