Hard to tell when this picture was taken. Usually we look at clothing, appliances, cars and architecture to date things, but this picture has none of that.
The woman third-from-the-left has a 1970s hair-do, but the guy she is looking at is thoroughly mid-60s. Could it be a time-space thing, where she is a modern girl from New York or California and her friends are from a small Midwestern town?
Where are we, if we are not at a nudist colony?
As for the material quality of the image, that too is hard to tell. Are we certain that this picture was shot on film?
Notice that all four are wearing medallions. These could be St. Christopher's medals, which were very popular amongst younger travellers in the 1970s.
But are they travellers? And if so, where did they come from? And where did they go from here?
