Since completing his PhD in Communication Sciences at the School of Communications and Arts of the University of São Paulo, when he developed research into the potential of football as a cultural heritage, Sérgio's collector's perspective has gained new shape, or rather, many shapes! Since then, he has become a regular at flea markets, such as the fairs at Bexiga, MASP and Praça Benedito Calixto, in São Paulo, and some of the objects in his collection come from these fairs and markets.
