In November 2017 at the Civic Gallery of Modern Art in Monfalcone, the exhibition "Boico - Cervi - Frandoli - Nordio - Naval interiors between art and design" was set up. A small exhibition dedicated to four architects of Trieste, it is a group that has distinguished itself after the Second World War as one of the major protagonists in the field of design and design of naval interiors. In this text we tried to deepen one of their ship design works, that of re-constructing the Conte Biancamano ship and also to investigate two examples of artistic interventions realized by artists within the most important public spaces of these ships, by the works of Mario Sironi and Marcello Mascherini. After the war, cruise ships were also one of the means through which, thanks to navigation, it was possible to make known the high quality of Italian design, architecture and art abroad
