Draft of a certificate - "A letter of thanks and blessing" for donors, and a "Shtar receipt – for the etrog". From "the holy yeshiva – the Mir Yeshiva (Minsk region in Russia), led by R' Eliyahu Baruch Kamai". Handwritten in Hebrew and German, on the official stationery of Rabbi Eliyahu Baruch Kamai. Mir, Sivan 1914.
the signatures on the draft for printing are the head of the yeshiva Rabbi "Eliyahu Baruch Kamai, Av Beit din and Rosh Metivta" and his son-in-law Rabbi "Eliezer Yehuda Finkel, Rosh Metivta".
Rabbi Eliyahu Baruch Kamai (1844-1917), famous Torah scholar in his times, teacher with many disciples. Served in the rabbinate of several cities in Lithuania-Poland and after Rabbi Eliyahu David Rabinowitz Te’omim [the Aderet] was summoned to serve in the Jerusalem rabbinate, Rabbi Eliyahu Baruch was appointed Rabbi of Mir and head of the yeshiva in his stead. His son-in-law is Rabbi Eliezer Yehuda Finkel (1879-1965), son of the Saba of Slabodka who in those years began to serve as Rosh Metivta and after the death of his illustrious father-in-law he headed the Mir Yeshiva in Lithuania and Jerusalem.
this draft was made in the spring of 1914, at the end of the Tsarist rule in Russia before World War I [possibly, the inscription "for the etrog" is a Jewish "invention" to enable collecting donations for the yeshiva at the time they were being pursued by Tsarist laws]. After a short while, the war erupted and the war front neared the area of Mir and the yeshiva fled to Poltava, Ukraine.
Leaf, 42 cm. inscriptions on both sides of the leaf. Fair condition, minor tears to paper folds.
