A crowd of people are gathered on a city street, possibly for a demonstration or march. The group is diverse, with people of different ages and ethnicities. Some individuals are carrying flags, banners, and signs with messages. One large banner reads "CTA" (Central de Trabajadores de Argentina - Workers' Central Union of Argentina). There is a marching band playing drums. The buildings around the crowd are old and have European-style architecture. The weather appears to be sunny and pleasant, and trees line the street. The crowd is moving in a procession, and it seems to be an organized event.
