Unoriginal holiday cards are worse than an eggnog hangover, and equally as nauseating. Don't fall into the holiday Hallmark humdrum. Original, creative cards provide a little extra holiday cheer, and this Christmas card is simple, fun and educational. Sure, you may think you know who Santa is, but he's hard to actually define. A joyful gift giver? A judgmental cookie glutton? This card takes a matter-of-fact crack at defining ole Saint Nick.
