Antonio Ascari and co-driver Erminio Castoldi at the wheel of entry #13, a De Vecchi with a 4-cylinder 90x100 bi-block engined 16/20 HP at the departure of the first Criterium di Regolarità di Modena. It took place i 23–29 April 1911 and was also called "Sei giorni di Modena".<a rel="nofollow" class="external autonumber" href="http://www.fondazionedevecchi.org/storia">[1]</a>  It was an endurance race, mechanical repairs not allowed. The co-driver is Erminio Castoldi, but looks like Enzo Ferrari (born 1898) from Modena, but he would have been only 13 years old.
