The Greeting Card Association is an international trade organization representing the interests of greeting card and stationery manufacturers. John Beeder, former president of the Greeting Card Association, says greeting cards are effective tools to communicate important feelings to people you care about: "Anyone feels great when they receive an unexpected card in the mail. For me, there’s nothing like a greeting card to send a special message. I’m proud to be a part of an industry that not only keeps people connected, but uses both imagery and the power of words to help us express our emotions.”
The custom of sending greeting cards can be traced back to the ancient Chinese, who exchanged messages of good will to celebrate the New Year, and to the early Egyptians, who conveyed their greetings on papyrus scrolls. By the early 15th century, handmade paper greeting cards were being exchanged in Europe. The Germans are known to have printed New Year's greetings from woodcuts as early as 1400, and handmade paper Valentines were being exchanged in various parts of Europe in the early to mid-15th century, with the oldest Valentine in existence being in the British Museum.
