I got a word from one of the boys in the photo, nowadays he is 62 tears old. I believe he is there at 8, so that the photo was taken around 54-55.

He swared the car is a Fiat with a second name which could be, as re remembers, Fiat Isabella, Fiat Isadora, or Fiat Fiorella.

There is no chance to be a brazilian production, so it must be an Italian made. The little badge just after the front wheel is much alike the italian "carrozieri" were used to do.
