The amazing Invisible Self Shelf from Dutch by Design isn’t a shelf at all – it’s a fake book that attaches securely to your wall. The Self Shelf is strong enough to hold the weight of a large number of books. Stacking it with your books makes it look like they’re floating on air. In a witty twist, the title of the fake book is 'Ceci n’est pas un livre' meaning 'this is not a book’. It'll be interesting to see if any of your visitors notice this subtle gag. I wonder if anyone will ask if they can read it!...
