Merry Christmas and Happy Holidays. Have you ever wondered where many of our holiday traditions came from. I did, and that's why I called an expert from Hallmark cards. He gave us the answers, and he also revealed how many things stayed the same over the years, like the increase in postage and the trends in the type of cards we send. He'll give away the year this interview took place when he mentions who was the President of the United States at that time.
