Folded save the date cards

In an earlier post, I mentioned that most orders for cards these days are for flat single cards; No folding. But I also mentioned that folded cards are still around and looking good. I submit as evidence these two folded save the date card ideas. These are white cards, approximately 4.25x5.5 / 5.5x4.25 inches when folded, full color printing on the front.

Example one: a photographic Tiffany box design.



Example two: meant to emulate the cover of a book, more information is printed inside, with the catchy "Book the Date" replacing the traditional "Save the Date".
