The 'Jewish book' was a siddur rinat yisrael (prayer book) with the name (Leah) לאה imprinted on the front. Since we're talking about the eighties, polling the NY metropolitan area to find which Leah had lost a siddur wasn't really feasible. Instead, he gave it to his sister, Leah.
Over the years, I've kept the siddur, davened (prayed) from it. It was really special to me - I've felt connected to that unknown Leah who lost her siddur.
Recently, I've realized that it probably is possible to find the girl (woman) who lost that siddur, so I'm going to post a picture of the inscription, and ask that everyone please send every friend whose Hebrew name is Leah to this blog post.
I really want to return the siddur to its rightful owner.
thanks for helping!
