At least 2,000 people joined the rally Saturday at Rio's Cinelandia Square, where a new street sign with Franco's name on it was put up. It replaced one that was taken down in early October by supporters of right-wing congressman Jair Bolsonaro, who won the first round of Brazil's presidential election last weekend.
