26 letters, on aerograms, short halachic responsa handwritten by R. Chaim Kanievsky. Bnei Brak, 1973-1978.

The letters were sent by airmail to the United States, in response to questions of R. Ephraim Greenblatt, author of Rivevot Efraim, who held a rabbinic position in Memphis, Tennessee. The letters are unsigned, but about seven of the letters have the name of the sender and his address handwritten by R. "Chaim Kanievsky". Most of the letters have the name of the sender and address ofrecipient handwritten by the Rebbetzin or others.

Short, concise responsa to various questions about Torah and halachic customs. In response to one of the questions, R. Chaim answers humbly: "I am surprised how it could occur to you that I would decide between the great. And in such cases we say that one who follows this opinion may do so, [and one who follows the other opinion may do so]". The letters also discuss the sending of books to R. Greenblatt, and receiving his book. In a letter dated Kislev 1974, R. Chaim apologizes for his delay in responding, "because they couldn't manage to buy letters".

In the letter dated Elul 1975, R. Chaim opens the letter with Shanah Tovah blessings: "May my friend R. Ephraim be written and sealed for a Shanah Tovah".

26 aerograms. Varying size and condition. Most in good condition.
