Letter handwritten and signed by R. Shemaryahu Yosef Karelitz, "to my dear beloved son R. Avraham Yeshayah and to his wife, my dear daughter-in-law", and a letter (in Yiddish) handwritten by his wife, Rebbetzin Rasha Leah, to their son R. Avraham Yeshayah Karelitz, author of Chazon Ish. Kosava, 22nd Shevat, 1907.

R. Shemaryahu Yosef Karelitz (1852-1916), author of Beit Talmud, served as Rabbi of Kosava, succeeding his father-in-law R. Shaul Katzenelbogen who relocated to serve as Rabbi of Kobryn.
His wife, Rebbetzin Rasha-Leah Karelitz (ca. 1854-1940), known for her piety and modesty and merited seeing all her nine sons and sons-in-law become famed Torah scholars and G-d-fearing individuals, including R. Avraham Yeshayah Karelitz, author of Chazon Ish; R. Meir Karelitz, Rabbi of Lyakhavichy and one of the heads of Moetzet Gedolei HaTorah; and R. Yaakov Yisrael Kanievsky, author of Kehilot Yaakov (the Steipler).
This rare letter is from an early period, when the Chazon Ish was about 30 years old, a yet unknown young man. The care and esteem the great father felt towards his son R. Avraham Yeshayah can be discerned between the lines of the letter.
