This is the back of the photo of my paternal grandfather Nisim Kalef with his three sons. The youngest was my father, Avram Kalef. The other two died very early. Nisim also died early so I don?t remember him. This photo was taken in the Cabinet Portrait studio in Belgrade in the 1900s. It says here: ?Nisim Kalef with sons. Youngest is Avram Kalef - husband of Antonija, father of Ljidije and Breda.?
