From October 4 to November 2, 2025, the Complesso Museale di San Francesco in Trevi will present "Un racconto Trevano color rame", an exhibition devoted to the works of Adelmo Testa (1920–2010), the Umbrian artist better known by the name Postiglione. The opening is scheduled for Saturday, October 4, at 6:00 pm in the Museum’s Conference Hall, with an introduction by Simone Cerquiglini, Carlo Roberto Petrini and Roberto Testa, followed by a guided tour of the fifty works on display.
The curators highlight how the exhibition also offers an opportunity to reflect on the future of repoussé copper, an art form with origins dating back to Sumerian civilization, which today risks disappearing, having been removed from academic teaching due to a lack of students interested in this discipline.
