National Card and Letter Writing Month is an annual effort to promote literacy and celebrate the art of letter writing. The writing, sending and receiving of letters, post cards and greeting cards is a tradition that has preserved the nation's history and changed lives. Unlike other forms of communications, card and letter writing is timeless, personal and immediately tangible.
