Cesare Pastore was a wealthy gentleman from Mantua, Italy, born in 1903, who raced as an independent Bugatti and Maserati machinery, in the late 1920s and early 1930. Highly successful in hillclimbs, he also competed in circuit and road races, including Montenero, Tripoli, Avellino and the Mille Miglia.
He even raced along with his eleven-year-old friend Tazio Nuvolari, also from Mantua, in the Coppa Perigina in 1927, sharing a Bugatti T37 - sixth place overall.
On 19 October 1924, Antonio Ascari won the Gran Premio d'Italia at Monza, leading home two other Alfa Romeo P2 cars driven by Louis Wagner and Giuseppe Campari. Different sources indicate that Campari shared the drive with one Cesare Pastore, who in August of that same year was reported to have taken part in the Grand Prix de l'Automobile de France at Lyon, driving a works Fiat 805 - retired. And in April 1924 Pastore drove the same Fiat in the Targa Florio.
In 1924 Cesare Pastore of Mantua was 21 years old. According to all the available sources, including Cesare De Agostini's authoritative book "Mantovani alla Mille Miglia", Cesare Pastore made his debut only in 1926, driving the family Lancia Lambda in the Cuneo-Colle della Maddalena hillclimb.
So in my opinion, very likely they were two different persons by the same name, or Campari's co-driver's given name was not Cesare.
