This is the back of David Kalef's class picture from the Jewish kindergarten in Belgrade. [Note: On the back it says that this is Samika Kalef.] I do not know who Samika Kalef was. On the back of the card it says: ?For a long lasting memory, our son Samika, on 10th May 1925. Samika Jakov Kalef, student at the Dorcol elementary school, near the Danube in Belgrade?
