Here's the fantastic new Italian limited commemorative edition of Jules Verne's Twenty Thousand Leagues Under the Sea designed by Paolo Orsacchini. It's printed on waterproof paper and enclosed in a clear pouch filled with real sea water. Collectors can either bust it out of its original packaging, dry it under the sun, and enjoy a classic read, or they can preserve this limited piece in all its designed glory.
Unfortunately I cannot find if it's available for purchase, so you'll simply have to marvel at the concept for now.
