770 Eastern Parkway is a building in Crown Heights, Brooklyn, that has served as the world headquarters of the Chabad-Lubavitch movement since 1940. It was the residence and primary work-space of Rabbi Menachem Mendel Schneerson, the seventh and final Lubavitcher Rebbe, from 1940 until his death in 1994.
The address has become so symbolic to the Chabad community that replica buildings (sometimes called 'mini-770s') have been constructed in cities including Jerusalem, São Paulo, Buenos Aires, Melbourne, and Milan. The numeral 770 itself functions within the Chabad community as a metonym for the Rebbe and the movement's institutional centre.
Tannenblut's Rebbe Bottle No. 770, priced at € 77,000, is the one-of-one apex of the Bereshit Series. Its numeral directly references 770 Eastern Parkway. The bottle carries a personal rabbinical dedication and encloses an original Rebbe Dollar.
