[1] letterhead. 24×15 cm. Letter written by Rabbi Yitzchak HaLevi Ruderman. It was sent to Rabbi Yitzchak Porat, and apologizes for a delay in sending thanks and greetings upon the receipt of his latest work – Mevo HaTalmud, due to Rabbi Ruderman’s three-month hospitalization. Rabbi Yaakov Yitzchak HaLevi Ruderman [1900-1987] was a disciple of the Alter of Slobodka. He founded and was Rosh Yeshiva of Ner Yisrael in Baltimore, Maryland, and was a member of the Moetzet Gedolei Hatorah of Agudat Yisrael in the United States. Very fine condition.
