A greeting card is an illustrated piece of card or high quality paper featuring an expression of friendship or other sentiment. Although greeting cards are usually given on special occasions such as birthdays, Christmas or other holidays, they are also sent to convey thanks or express other feelings. Greeting cards, usually packaged with an envelope, come in a variety of styles. There are both mass-produced as well as handmade versions that are distributed by hundreds of companies large and small. While typically inexpensive, more elaborate cards with die-cuts or glued-on decorations may be more expensive.
Hallmark Cards and American Greetings are the two largest producers of greeting cards in the world today (both are U.S-based companies).
In Western countries and increasingly in other societies, many people traditionally mail seasonally themed cards to their friends and relatives in December. Many service businesses also send cards to their customers in this season, usually with a universally acceptable non-religious message such as "happy holidays" or "season's greetings".
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.”
Counter cards: Greeting cards that are sold individually. This contrasts with boxed cards.
Standard Greeting Cards: A standard greeting card is printed on high-quality paper (such as ), and is rectangular and folded, with a picture or decorative motif on the front. Inside is a pre-printed message appropriate for the occasion, along with a blank space for the sender to add a signature or handwritten message. A matching envelope is sold with the card. Some cards and envelopes feature fancy materials, such as gold leaf, ribbons or glitter.
Photo Greeting Cards: In recent years, photo greeting cards have gained widespread popularity and come in two main types. The first type are photo insert cards in which a hole has been cut in the centre. A photo slides in just like a frame. The second type are printed photo cards in which the photo is combined with artwork and printed, usually on a high-end digital press, directly onto the face of the card. Both types are most popular for sending holiday greetings such as Christmas, Hanukkah & for baby showers.
