I am the owner of the original photo.
Mario Faina is actually the guy, partially concealed, on the passenger seat on the original poster photo.
Mario, my granpa, always reffered at that car as a Jaguard.
In the last 20 or so years, I always thought he was mispelling Giaur, so I m very surprised to hear the word Jaguard again.
The fun fact is that I have an handwritten note from the late 80s where he calls that car a “Jaguar”.
If i recall right, the picture is from Il Giro di Sicilia, 1950. Mario died in 1991.
Best regards.
