The performances presented on Republic Square (today's Ban Jelačić Square) in Zagreb in 1971 are the first work from the "Casual Passer-by" cycle. Another performance was done separately on Marshal Tito Square (today's Republic of Croatia Square) on the same day, when a large poster (portrait) of a random passer-by was mounted. Three large posters (portraits) showing photographs of an older man, an older woman and a young girl were hung on Republic Square. The posters (portraits) aroused great interest and confusion among the passers-by waiting for a tram.

It was a subversive performance in a public area, otherwise intended for officials, where the artist hung portraits of random passers-by and in that way questioned the established forms of communication in the public space of a socialist state.

The Museum of Contemporary Art in Zagreb owns five photographs on one background that testify to this event - called the "Casual passers-by I met at 1:15, 4:23, 6:11 p.m.".
