[2] His work during the next several years consisted mainly of Realist portrait busts created by casting, notably that of former President José Figueroa Alcorta for its placement over the latter's La Recoleta Cemetery crypt.

[1] He then secured two solo exhibitions in Buenos Aires, including a 1928 Friend of the Arts event inaugurated by President Marcelo Torcuato de Alvear, who commissioned Fioravanti to create decorative reliefs for the Casa Rosada's interiors.

He earned increasing renown in the French capital, and in 1934 was honored with a solo exhibition at the Galerie nationale du Jeu de Paume.

[2] Establishing an atelier in seaside La Lucila del Mar, he created numerous landmark monuments in the ensuing years, including memorials in Buenos Aires to Presidents Nicolás Avellaneda and Roque Sáenz Peña (1935–36), Venezuelan General Simón Bolívar (1942), U.S. President Franklin Roosevelt, as well as two sea lion effigies guarding an esplanade in Mar del Plata (1941), a memorial in Montevideo to Uruguayan General Fructuoso Rivera (1965),[5] and to General Manuel Savio, father of the Argentine steel industry, in Villa María, Córdoba (1969).

[6] Another significant series of Fioravanti's work would adorn the National Flag Memorial, a landmark overlooking the Paraná River in the city of Rosario.
