#MarioPetrobelli

Mario Petrobelli was an ​Italian racing driver who participated to VI Circuito Moto-Auto di Senigallia, part of the I Settimana Motoristica delle Marche, on August 20, 1950 finishing third overall, contributing to the success of Scuderia Ferrari at the event. Petrobelli's use of the pseudonym "OLOAP" (which is "Paolo" spelled backward) reflected a common practice among drivers of that era, who often used aliases for personal or professional reasons.

We'll publish a biography on him on the occasion of his anniversary or when it will be reached a sufficient number of cars.
