I'm a bit at a loss. I know this won't let me sleep tonight.
Given the Boneschi Fiat, I hazard a guess it's 1950 and there is a car show going on in Venice.
The cars in the left row are all show cars. So are the two poking their noses into the pic from the bottom.
They have strong Ghia overtones, no? The right one could well be a Ferrari 195 Inter.
The cabriolet with the two large instruments is very Pinin Farina, don't you think?
