A letter of recommendation signed by "The Rebbe HaRytz" [Rebbe Yosef Yitzchak Schneersohn] of Lubavitch. Brooklyn, 1949. Signature in his own handwriting with the addition of the words [who blesses] "with material and spiritual (blessings)".
One year before his death, the Rebbe HaRytz started to sign the letter "yud" of his second name (Yitzchak) in Ashuri (square) script, and this was an amazing hint to his near passing on the 10th of Shevat (his son-in-law the Lubavitcher Rebbe explained this fact at length in the gathering on Shabbat Va'eira 1951 - see attached material). This letter was sent a half a year before his death, where his special signature with the square "yud" can be clearly seen.
The Rytz, Rebbe Yosef Yitzchak Schneersohn (1880-1950, Otzar HaRabbanim 8887), the sixth Chabad-Lubavitch Rebbe, founder of Tomchei Temimim Yeshivot together with his father Rabbi Shalom Dov, became Rebbe in 1920. He was imprisoned by the Communist government and released in 1927, whereafter he reached Poland and in 1940, Brooklyn. Some of his works: Sefer HaMa'amarim, Likutei Devorim etc. His son-in-law was Rabbi Menachem Mendel Shneersohn - The Lubavitcher Rebbe.
