Do you recall the very first formal wedding invitation you ever received? The oversized envelope stuck out, all creamy and smooth, elegantly addressed, perhaps penned in calligraphy -- like a gift -- one envelope slipped inside another, a wisp of tissue paper… and finally, the exquisitely worded invitation itself. You may have run your fingers over the letters, artfully raised from the page, the work of fine copper plate engraving. This classic invitation has been the traditional choice for generations, yet it was by no means the first form of wedding invitation.
