On January 10, 1910, a teenager from Nebraska stepped off a train in Kansas City, Mo., with little more than big dreams and two shoeboxes of picture postcards. From those inauspicious beginnings an iconic brand was born. Billions of well-wishes later, Hallmark Cards, Inc., celebrates its own 100th birthday in 2010 with a nod to the past, a focus on the future, and the grandsons of that Nebraska teenager at the helm.
