Early postcard sent by the Admo”r of Erlau immediately after the Holocaust, to Shlomo Sofer, his cousin, in which the Admo”r informs him of his desire to anthologize responsa sent to his father, but “during the deportation, they were lost.” He requests of his cousin to appeal to rabbis with whom his father corresponded to resend their responsa so that he can print them. The request was to appeal to: Rabbi Akiva Sofer, Rabbi Yosef Tzvi Dushinsky, the gaon of Tchebin, and the author of Dover Meisharim.
