The Casual Passer-By Collection by the Bosnian-Herzegovinian conceptual artist Braco Dimitrijević consists of eight photographs and two posters (portraits) created in Zagreb and Belgrade in 1971. The photographs and posters (portraits) were the foundation of his three performances from the "Casual Passer-by" series staged in Yugoslavia. They were subversive performances in which the author hung portraits of chance passers-by in public spaces, otherwise intended for executives, in this way questioning established forms of communication in the public space of a socialist state.
