It was called Soffio di Satana, or "Devil's Breath" for a reason obscure to me.
A few years ago Bonhams auctioned one of the three cars built. Its web page quotes from "Hull & Slater’s standard work, 'Alfa Romeo – A History'” as follows:
"This aerodynamic saloon by Touring of Milan is one of just three built and is the only example known to survive. The first was commissioned by the renowned Italian poet, Gabriele d’Annunzio, who helped design its lines and gave it its name (“Devil’s Breath”). The second was delivered to celebrated soprano, Gina Cigna, and the third, this car, was built for Barone Mariano Pagliaro who specified “Blu Notte d’Oriente” livery with blue leather upholstery, to match his coat of arms. This car was raced in the 1934 Targa Abruzzo, winning the Turismo class before delivery to the Baron."
Gabriele d'Annunzio was a writer, adventurer and politician, still well-remembered in Italy. He was quite capable of the Devil's Breath naming. That might or might not be true, but it makes for a good story, so I'll go along with it for now.
The above quotation states that only one of those cars seemed to have survived. Since then, d'Annunzio's emerged and went on auction. The majority of the images below are of it.
