  • This Happy Birthday stamp conveys exuberant greetings by calling to mind the childhood excitement of a birthday party.
  • In the digital illustration featured on the stamp, the word "HAPPY" appears most prominently in all capital letters, with each of the five letters inspired by a different party decoration: a red and green pinata, an orange and yellow striped birthday hat, a red piece of frosted cake, a green birthday candle, and an orange balloon sculpture.
  • The word "BIRTHDAY" appears below it in blue, with Forever and USA centered in smaller red lettering at the bottom. Surrounding all of the design elements is a flurry of multicolored ribbons and confetti.
  • The Happy Birthday stamp was issued as a Forever stamp. This Forever stamp is always equal in value to the current First-Class Mail one-ounce price.

Description

This Happy Birthday stamp conveys exuberant greetings by calling to mind the childhood excitement of a birthday party. In the digital illustration featured on the stamp, the word "HAPPY" appears most prominently in all capital letters, with each of the five letters inspired by a different party decoration: a red and green pinata, an orange and yellow striped birthday hat, a red piece of frosted cake, a green birthday candle, and an orange balloon sculpture. The word "BIRTHDAY" appears below it in blue, with “Forever” and “USA” centered in smaller red lettering at the bottom. Surrounding all of the design elements is a flurry of multicolored ribbons and confetti. The celebration of birthdays in the United States has its origins in a wide array of cultural traditions. Some ancient civilizations observed the birthdays of prominent figures or celebrated rites of passage, and well-wishes and gifts have long been associated with bringing about good fortune. Folklorists and historians claim to see the origins of birthday parties in older practices that resemble our customs, such as candles on a cake, which existed in some form in both ancient Greece and early modern Germany. When we gather to sing, brighten our spirits with candles, and make a wish, these deeply rooted rituals connect us to loved ones and invite everyone to share in the birthday fun.

MAKE SOMEONE HAPPY
Size: 20 Stamps
I write cards and letters to people that require a stamp. I love commerative stamps and enjoy using them for each card or letter. I was happy to find these Happy Birthday stamps. USPS used to have them. They were different, but they were Happy Birthday stamps. These came out around 2020 and I came upon them on a scam site. I didn't know it was a scam site until I noticed a few "give away" features. So, I reluctantly gave up what I had hoped to order. And then, Amazon had some! I was thrilled! These stamps are so much fun to add onto birthday cards! I know people don't do letter writing/card sending any more, but I do it regularly and am really happy to have found these happy stamps! ... show more

Perfect For Birthdays!
Size: 20 Stamps
I didn't even know they made birthday card stamps! They're a little expensive but I don't care I love them, and they're going to just be the icing on the cake haha! They were put carefully in an envelope before packaging for protection. I received other stamps that I ordered that had just been thrown in the packaging and they were creased. I'm very pleased with this purchase! ... show more
