Emilio Materassi and his Itala Special, supposedly at Circuito Savio near Ravenna in 1924, which would be on 25 May 1924<a rel="nofollow" class="external autonumber" href="http://www.dlg.speedfreaks.org/archive/gen/1924.html">[1]</a> However, the entry #31 is different from that source (he had #31 in other races, but not in the Savio race). The source claims that we see the "Hotel Classensis" behind, which was demolished in 1955. It is in Ravenna. And we see the Sant'Apollinare in Classe (a church).
