Three men and a Maserati 4CLT racecar (active 1947/48) next to a company truck also advertising for "Candele" (spark plugs) by Maserati, which 1947 to 1960 also had an independent spark plug manufacturing company. Most likely, this is a 1947/48 picture. The racing driver looks like Giuseppe Farina and the two others look like Ernesto Maserati and Bindo Maserati.
