The image is a poster for a festival called "20 Fêtes des Remparts Dinan". The poster is displayed on a stone wall in a store window. The background of the poster is a colorful illustration of a medieval castle with a group of knights on horseback in front of it. The knights are dressed in full armor and are holding flags and banners. The castle is surrounded by trees and there is a bird flying in the sky. The text on the poster reads "Nouveau! Appli mobile de la fête!" which translates to "Appli mobile of the festival!" in English. There is also a QR code on the bottom right corner.
