Calvino is a Wizard

I recently found a piece of paper stuck inside the used copy of Calvino's If on a winter's night a traveler, which I bought this summer and have just begun reading. It contained this note:

"Calvino is a wizard"
and this book is an enchantment
let it capture you

Very cool. If I ever donate my books to a library or used book store, I think I'll do something similar.
