The image is a poster for an event called "Alternatiba Rennes" which is taking place on 27th June 2015. The poster is displayed on a window in a store window. The background of the poster is green with white text and illustrations. The title of the event is written in large, bold letters at the top, followed by the date and time of the day. Below the title, there is a smaller text that reads "Changéons le systeme pas le climat!" which translates to "Change the system as the climate" in English. 

The poster also includes the names of the participants and the date of the conference, as well as the location of the venue. There are also illustrations of trees and other natural elements, such as a mountain range, a river, and a forest. At the bottom of the page, there are logos for the event's sponsors, organizations, and sponsorships.
