After a few days of search, at least 6 people in the Sanzetti pictures (see post: Sam Sanzetti, Shanghai photographer) have been found. You can find some pictures of these people and their original photographs at the following link on Yahoo China: http://news.cn.yahoo.com/newspic/news/19184/?f=E364_3_1
A regular reader of this blog, Ms Liliane Willens (see post: A date with Liliane) had also been photograph by Sam Sanzetti herself and her family. She is currently contacting the Shanghai Israeli Consulate people in charge of the exhibition.
