Aunt Fran's will is at the First National Bank (lit. Dai-Ichi Kokuritsu Bank), vault box #1407. This was the first bank and the first joint stock company ever to be established in Japan, in 1873.
During the episode, Aunt Fran wears eight different 1960s classic-look outfits, including a kaftan (a loose evening gown). Sally Burton also wears eight different outfits, all of them in synch with the 70s fashions.
