This paper analyzes the advertising campaign Sócio Olímpico-Cadeiras Cativas, created by Osvaldo Moles for the São Paulo Futebol Clube. Ran from 1955 to 1959, the campaign sought to raise funds for the construction of Morumbi Stadium, through the sale of club memberships. The newspapers' advertisements showed an intense promotion of the Sócio Olímpico title as a factor of social distinction. Nonetheless, numerous elements have revealed that, on the contrary, the Campaign had a clear massified dimension, supported also by widely accessible purchasing conditions. The paper thus aims to expand the investigation of the publicity and commercializing and comprehend the coexistence of the massive and differentiate within the same propaganda.
