Nice Paris 1953 photo !
Reasonably sure the Alfa wasn't at Paris
However there was a Ghia Alfa Romeo similar to yours on the large Ghia stand at Turin show 1953.
It appears to have a metallic shade & has whitewall tyres.
Shared the Ghia stand along with Ghia Fiat Abarth , Ghia Dodge Firearrow , Aurelia Boano Junior 2 ,etc
I think the original Supersonic ,the Alfa Conrero was supposed to be there also , but have never seen photos !
