Give a book, regalalo by train

There was an initiative long ago. It was a book on the train to leave so the next traveler found it and read it and then leave it at another. Maybe it's for more than a year that has started and so much nicer then be on a train (late, but looks a bit ') with a book next to it.

I happened one of the photo, Grazia Deledda. A little 'messy, definitely tired: I wonder how many have read or just peeled. And the culture goes.
