Is that the first-ever spoiler on the tail?
It's a spoiler but I'm sure it doesn't date from the 1950's!
Someone of questionable taste clearly seems to think it's a good idea to customize a Touring-bodied Alfa 1900 CSS..
I don't know if the front was always like that with no Alfa shield either; maybe the same person in modern times thought it might improve the frontal appearance to take the shield away? I certainly haven't seen any period pictures of a Touring Alfa looking like this; has anyone else?
