The present contribution takes a relatively unconventional angle for its investigation of the abrupt shift in Czech unofficial journalistic culture from severely repressed samizdat before November 1989 to significant social force in the first years of the subsequent decade. It takes as its locus the Prague office building at the address Bolzanova 7, a former Czech Rail property assigned to the samizdat-based independent journalistic agency Informační servis at the end of 1990.
