The performance presented on Marshal Tito Square (today's Republic of Croatia Square) in Zagreb in 1971 was, together with the performance on Republic Square (today's Ban Jelačić Square), the first work from the "Casual Passer-by" cycle. The poster (portrait) ˝Casual passer-by I met at 12:15 p.m.˝ was used for the performance. This poster (portrait) and two photographs of the event are owned by the Museum of Contemporary Art and are part of its permanent display. This performance aroused both the interest and confusion of Zagreb’s citizens, just as the one on Republic Square did.

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.
