Photograph of a woman depicted in the description as Mrs Zwifel

The full-figure portrait of a woman described on the back as 'Mrs Zwifel' by Halina Mamelok, née Baruch. She is wearing a dark evening dress which falls to the ground. She is photographed against a wall, probably covered with fabric; we can see a framed photograph (?) hanging on the wall. The woman is standing upright, her hands joined behind her back, looking into the camera with a half-smile. Apart from the name, nothing is known about this person.
