Since August 2021, the Italian artist Ilaria Vinci has been occupying the outdoor space of St.Gallen in collaboration with the Kunst Halle. Under the title A Great Cosmic Joke with No Punchline, six different, yet coherent pictorial landscapes are continuously installed on the city's cultural advertising columns. On the one hand, the works occupy advertising space and, on the other, open up insights into individual as well as collective fantasy worlds to passers-by. In the process, the public space as exhibition space takes over the function of the museum and at the same time eludes institutional conditions. The artworks become ephemeral, everyday and accessible to all.
