The small passport-like document gave Seidamen, and tens of thousands of other Jewish refugees, a way to escape the horrors of Nazi-controlled Europe and forge a new life in Shanghai.

Now, nearly 70 years on, the piece of paper that surely saved her life is now on display in a collection of artifacts highlighting a chapter of Jewish history in China that few people know of.
