Yes, from the same article, as I said:
"The Spider was launched at the 36th
Geneva Motor Show in March 1966,
[8] and together with the
Giulia Sprint GT Veloce tested by the press at an event organised in
Gardone Riviera.
[9] To choose a name for the spider Alfa Romeo announced a write-in competition, offering an example of the new car as a prize.
[14] Over 100 thousand ballots were sent in, the great majority from Italy; the winner was Guidobaldo Trionfi, a man from
Brescia, who proposed the name "Duetto" (duet).
[14] However it could not be officially adopted due to trademark issues, and the car was named simply
Alfa Romeo Spider 1600"
Notice that this entry is not 100% correct, in Italy until 1967 they did market it as a Duetto until they lost the trademark battle - from then on it was always Spider, everywhere.
I am a serial alfaholic Lanny, I tend to know what I am talking about when it comes to this nonsense.
