I am really impressed that "diggingdeeper" found not only the location but also a picture from almost the exact same place ...
Thanks for help !
Its a disease - I can't resist a challenge, you've no idea how annoyed/frustrated I am that I haven't identified the individuals as yet, both of them are celebrities I recognise. I've checked all the Eva Gardener and Susan Hayward pictures to see if they had a slightly different "look" at some time, both have similarities but this girl has a bit of SE Europe look (imho)
I'm a bit concerned at that Sunbeam being in Italy, it would be a very rare event in the 1950's so the picture may be an overlay.
