Name-paper Amrit -- Siddhi 1970
The "letterhead" for this name-paper is unusual, possibly unique. We have seen blank pieces of paper elsewhere ... this is the first and possibly only example of Osho's ripping up a letter addressed to him and using the back side. (The name and address of the sender have been redacted.)
As a name-paper, it is also so far unique, being the first known instance of names for two people on the same name-paper. For all that Osho has talked about individuality and against the institution of marriage, it is almost as if he is blessing this marriage.
