The image shows a large red banner hanging on the side of a building. The banner is rectangular in shape and has the words "25 anos a defender os ideas de abril" written in white letters. The building appears to be old and dilapidated, with peeling paint and broken windows. There is a large arched window on the right side of the building and a balcony on the left side. The sky is overcast and the overall mood of the image is somber.
