Well, someone actually used one of those things (or one he manufactured himself) to stash emergency cash and credit cards and almost 20 years later his brother donated it to a library book store in Maryland. Maryland's Gazette.net has the story - including the surprise happy ending:
Schnitman said his younger brother, Jeffrey Schnitman, had kept a "rainy day fund" of cash and credit cards in the book. He would not disclose the full amount of money.Frankly, the most surprising thing about this story is that Mr. Schnitman got his money back (click on the link for that part of the story) - maybe criminals don't frequent used book stores?
When his brother died 17 years ago at the age of 36 from Crohn's disease, Schnitman kept the faux book along with its contents on his own bookshelf.
But in the months following his move from Gaithersburg to Chevy Chase last July, Schnitman accidentally donated the hollowed-out book and several others to the Montgomery County Friends of the Library's used bookstore on Boiling Brook Parkway.
"So I realized probably six weeks later that the book was missing and I went to the bookstore and magically someone had found it and turned it in," the 56-year-old said.
