This essay aims to present in an organic form the work of interior design, enriched by an important nucleus of artistic creations, on board the Lloyd Triestino’s motorship Victoria, entered in service 27 July 1931 from Trieste to Alexandria. After an introduction that summarizes the history of the maritime connection between the two Mediterranean cities and the commercial reasons that led to the building of the ship, the main technical and aesthetic characteristics of its construction project are described. The collaboration between the naval engineer Nicolò Costanzi and the architect Gustavo Pulitzer Finali is also emphasized: the two protagonists of the construction of one of the most beautiful and innovative Italian ships between the two wars. The text continues by analyzing the advertising campaign for the promotion of the new motorship, where emerges the work of Giuseppe Riccobaldi, an important Genoese advertising graphic designer. This is followed by the description and analysis of the first and second class lounges, designed mainly by Gustavo Pulitzer and by the Ducrot Company from Palermo. The article points out the formal and aesthetic balance achieved by the innovative architectural project and the numerous works of decorative art created by various artists such as the sculptors Libero Andreotti and Maryla Lednicka, the architect Gio Ponti’s for the ceramic lining, Pietro Chiesa for the stained glass windows and the painters August Cernigoj and Elena Fondra for the mural decorations.
