Fontana continued to create works in line with Fascist ideology and repeatedly accepted commissions from the party and government.
In 1929, for example, he created a 'Fascist Victoria' holding a victory wreath, which was exhibited at the Venice Biennale a year later. In 1936 Fontana created the monumental sculpture group 'Vittoria' for the Hall of Fame at the VI Triennale in Milan. In 1937 he participated in a competition for a bust of Mussolini. In 1938-39 he was commissioned by the architects Giovanni Albricci, Mario Tevarotto and Marco Zanuso to design a ceiling for the Milan Fascist League Palace (now the headquarters of the Carabinieri). Fontana designed a relief entitled "Volo di Vittorie" (Flight of the Goddesses of Victory).
At the beginning of 1940, Fontana left Italy and travelled to Argentina to take part in a competition for the national monument in Rosario. Fontana therefore did not directly experience the Second World War, which Italy entered on 10 June.
