The most critical clue is a poster visible in the background. The partially legible text '...ali ne i na plućima' is Croatian for '...but not on the lungs', a known slogan from an anti-smoking campaign in Croatia. This strongly places the location within the country. Furthermore, the distinctive architecture of the stairwell—featuring a stepped, layered underside of the stair flights, grey metal railings with glass panels, and a cylindrical wooden handrail—is an exact match for the main stairwell inside the Faculty of Humanities and Social Sciences (Filozofski fakultet) at the University of Zagreb. This identification is confirmed by numerous publicly available photographs of the building's interior.

Based on the Croatian language on the poster, another major Croatian city with a large university is a possibility. The architectural style, common in public buildings from the mid-to-late 20th century, can be found in cities like Split. While not a specific match, a faculty building at the University of Split could plausibly have a similar interior design.

The language on the poster belongs to the Serbo-Croatian language group, making neighboring countries like Serbia a possibility. The architectural style is very typical of the Yugoslav era and can be found in many institutional buildings across the former Yugoslavia, including at the University of Belgrade. However, this is less likely as the specific anti-smoking campaign is more strongly associated with Croatia, and no direct architectural match was found.
