Fantastic
Just a detail (I'm over-meticulous...)
The race is the 1956 Mille Miglia, in the penultimate picture there is a blue Fiat 500 (with a red dressed girl standing), near the Eugenio Castellotti's Ferrari 290MM #548 and the parked Alfa Romeo Giulietta Spider #425 (Consalvo Sanesi?).
It's impossible, because the first "Fiat Nuova 500" was sold only on July 1957.
(perhaps that girl was Engineer Giacosa's daughter, testing the prototype...

)
