Handwriting of the Author of "Ma'ayana shel Torah", Rabbi Alexander Zusia Friedman - circa 1930 - Extremely Rare

A letter sent by Rabbi Arye Langleben, the rabbi of Sertzin, to the well-known rabbi, Rabbi Alexander Zusia Friedman, the author of "Ma'ayana shel Torah". On the document, Rabbi Friedman added several words in his handwriting.
In the letter, Rabbi Langleben writes: "how while I was in the city of Widawa for purposes of fundraising, the dear Rabbi Shlomo Reuben Glester helped us greatly … and I have heard that he is working with total devotion for all that is dear to us - and although he is persecuted because of it, that is, he is a follower of Alexander - well, it is fitting to help him in whatever we can".
Under this, Rabbi Alexander Friedman wrote in his handwriting: "To the Aliya department, please take into consideration the deliverer of this letter who is a societal activist…" Rabbi Friedman signed in his handwriting. It should be noted that it is extremely rare to find the handwriting of Rabbi Friedman, although his composition is well-known and one of the inalienable assets of rabbinic literature.
