Hana Gasic's photo of a woman in black hat and coat posing for a portrait

This picture was taken in Sarajevo in Atelier Helios. It was sent to my mother, Flora, or 'To my little Florica,' as it says on the back in Serbian. It is signed, 'Your Miss Pololika Prinz,' and dated Sarajevo March 29, 1926. The identity of the woman in the photo and her relationship to my mother is unknown.
