A large group of people is seen walking along a street, possibly in a procession or demonstration. Many individuals are carrying flags, primarily red and purple, which billow in the wind. The flags display the acronym "COS" and the full or partial text "COORDINADORA OBRERA SINDICAL," along with the number "20." In the foreground, three people are walking away from the camera, seen from behind. One person on the left carries a purple flag. The central figure wears a blue and red jacket with a dark green backpack. The person on the right wears a light-colored top, jeans, and also has a backpack or bag strapped across their back. In the background, a distinctive, tall, egg-shaped skyscraper with a mosaic-like facade dominates the skyline. This iconic building is the Torre Glòries (formerly Torre Agbar) in Barcelona, Spain, providing a strong geographical cue. The sky is overcast, indicating a cloudy day, but visibility is good. The event appears to be taking place during daylight hours. The scene suggests a public gathering, possibly a labor or union-related demonstration given the text on the flags.
