Leon Levi's unknown relative

I don?t know who the person in this picture is. I assume that he is either my wife's father, Mr. Bunjulov, or a relative of my father whom I don?t know.The picture was probably taken in Greece. I don't know anything about my ancestors. My parents never talked about them or if they did I don't remember. I only know that my father's family moved to Thessaloniki some time before World War I. During the Holocaust all my father's relatives were deported to one of the concentration camps - I don't remember which one - and were killed there. Not a single person survived.
