large group of people protesting on a city street. In the foreground, people hold signs with messages like "EQUIPARAÇÃO DOS VALES REFEIÇÃO DOS APOSENTADOS MUNICIPAIS E DO TCM" and "JUSTIÇA PARA OS READAPTADOS". Many wear white t-shirts with "SOMOS 100% SUS" printed on the back. A yellow truck with a raised platform serves as a makeshift stage, where several individuals stand, addressing the crowd. One person, wearing a red top, speaks into a microphone while others take pictures. A red flag bearing the word "SINDSFUMG" is visible. Buildings line the street, and overhead power lines are strung between them. The sky is overcast.
