Thanks. I have that book.
An even better one on the same subject is The Tarim Mummies by Victor Mair.
BTW, the oldest paper ever found was found with this area and it has Tocharian A written on it.
I'd be interested in seeing the source for that. It would seem to be a chronological impossibility, as the earliest Tocharian A documents date from the 6th century CE, which is centuries after even Cai Lun paper.(SRC)
