Every February 14, across the United States and in other places around the world, candy, flowers and gifts are exchanged between loved ones, all in the name of St. Valentine. But who is this mysterious saint, and where did these traditions come from? Americans probably began exchanging hand-made valentines in the early 1700s. In the 1840s, Esther A. Howland began selling the first mass-produced valentines in America. Howland, known as the “Mother of the Valentine,” made elaborate creations with real lace, ribbons and colorful pictures known as "scrap." Today, according to the Greeting Card Association, an estimated 1 billion Valentine’s Day cards are sent each year, making Valentine's Day the second largest card-sending holiday of the year. (An estimated 2.6 billion cards are sent for Christmas.) Women purchase approximately 85 percent of all valentines.
