This is the back of the photo of my cousin, Josko Kalef, taken in Belgrade on 17th January 1925. He was the son of my paternal granduncle Avram Kalef. The family, apart from Josko's sister Regina, perished in the Holocaust. On the back of the photo it says: ?For long-lasting memory I give this to my uncle and aunt. From Josif J. Kalef?
