Photograph of four unrecognised people by a car

The photograph of a group of four elderly people standing by a black car; in the background, there is the lower floor of a tenement house, possibly on the side of the courtyard, since a ladder can be seen behind the car. The lack of any signs or captions makes it impossible to formulate any assumptions concerning the identity of the people depicted in this photograph from the collection of Halina Mamelok (Kamińska) née Baruch.
