This article describes the beginnings of the lesbian, gay, bisexual, and trans (LGBT) periodical press in Brazil. Structured around Benedict Anderson's concept of imagined communities and Jurgen Habermas's theory of the public sphere, it shows how a marginalized group constructed a positive sense of identity and set out to change popular culture by challenging prej udice and discrimination. The analysis concentrates on the mimeograph journals circulated among gay men in the 1960s, such as O Snob, and the pioneering community newspaper Lampiao (1978)(1979)(1980)(1981), examining their treatment of gender and sexuality through issues such as cross-dressing, sex roles, and street prostitution. Through their explorations of the LGBT sub culture and innovative use of discourse based on popular slang, these pub lications helped create a new space for the public discussion of sexuality as well as greater cultural awareness of a shared but diverse community.
