The first picture: Tishrei Blessings
The Rebbe kisses the Sefer Torah as it is being returned to the ark, the Monday or Thursday after the holiday of Simchas Torah. The Torah reading took place downstairs at 770; the Rebbe is seen here descending from the lectern to meet the Sefer Torah. Once the ark doors were closed, the Rebbe returned to his room. In those days, the Rebbe did not attend the daily morning service but did join the regular prayer group for kriah.
The second picture: Let it Be a Memorial
The Rebbe holds the Sefer Torah on 10 or 22 Shevat, one of the Yahrtzeits for, respectively, his father-in-law the Previous Rebbe or the Rebbe’s wife, Rebbetzin Chaya Moushka. The Rebbe will carry the scroll to the bimah from which to be read.
The third picture: Special Days
In this photo, circa 1963, the Rebbe is called to a Torah reading in an unfinished downstairs 770. This event most likely took place on one of the days the Rebbe would pray the morning service in public: Erev Rosh Hashonoh, Erev Yom Kippur, the intermediate days of Passover or Sukkos, Purim, or a Yahrzeit (anniversary of a loved one’s passing).
