Responsa by Rabbi Moshe Sofer, Rabbi of Erloi, by his son, Rabbi Yochanan Sofer with his supplements. Budapest, [1949]. The first book published by Admor Yochanon Sofer of Erloi, published in Hungary while he collected Holocaust survivors, established a yeshiva in Erloi and served as rabbi. He later immigrated to Israel. At the beginning of the book he includes a eulogy for his father and family who were killed in the Holocaust. Very fine condition.
