Mid-Century design is my favorite. I love the vintage, the lines, the colors! I love Mid-Century Christmas, especially. It just evokes the nostalgia and sweetness of the holiday so well. Wanted to share these Mid-Century vintage Christmas cards with you ... they are located here: Mid-Century Christmas cards at Birdhouse Books. Couldn't you just picture these cards lined up on Don and Betty Drapers' fireplace mantle on Mad Men?
