Happy St. Valentine's Day

About.com's "Honeymoons and Romantic Getaways" writer Susan Breslow Sardone points out that the first Love stamp was issued by the Postal Service in 1973 with a denomination of 8 cents and an iconic design by pop artist Robert Indiana.

Since then, Love stamps have featured a wide range of subjects, including flowers, animals, cherubs and love letters as well as abstract designs.

The 2004 Valentine's Day stamps featured heart- shaped candies that said "I Love You." It was created by Michael Osborne of San Francisco. The design was based on the popular Valentine's Day candy made by the New England Confectionary Co. (NECCO) which made a special run of the candies that year.

On her site, Susan also offers up a selection of vintage Valentine's Days postcards that you can e-mail to a friend or lover. To view them, click here.
