Letter of Torah, dealing with Tractate Zevachim, in the handwriting of Rabbi Chaim Kanievsky, to his father-in-law Rabbi Y.S. Elyashiv. "My teacher, my father-in-law, the famed great gaon Rabbi Y.S. Shlita", signed: "His son-in-law ben Rabbi Y.Y. Shlita." Zichron Meir [Bnei Brak], Tevet 1953. Between the lines are (penciled) notes of Torah thoughts, in the handwriting of Rabbi Elyashiv, a draft of his response to this letter. On the reverse side is an interesting family letter, handwritten and signed by his wife, Rebbetzin Bat-Sheva.

She relates that Rabbi Chaim studies with him daily for a few hours. She inquires as to the health of her father and mother, the other children and her grandmother [Rebbetzin Chaya Musha, mother of Rabbi Y.S. who died in the month of Iyar 1954]. She especially asks that "someone from home, come" to visit them in Bnei Brak. Leaf, 19.5 cm.
