The Postal Service is issuing two Forever stamps that are perfect for mailing anniversaries, birthdays, proms, and other life-celebrating invitations enclosed with RSVP cards.

The new Celebration Corsage two-ounce Forever stamp can accommodate the weight of heavy invitations for birthdays, weddings, anniversaries, and other celebrations, oversized greeting cards for all occasions, and mailings such as small gifts that require extra postage. The stamp image is a photograph of an arrangement of ranunculus with accents of hypericum berry, Astrantia, and seed eucalyptus.

Similar in design to the new two-ounce Celebration Corsage stamps, the Celebration Boutonniere First-Class Forever stamp can be used for wedding RSVP cards. It is also perfect for party invitations, thank-you notes, announcements, birthday cards, Father’s Day cards, and other occasions when a beautiful stamp is fitting. The celebration boutonniere stamps art features a photograph of an arrangement of ranunculus, with floral accents of succulents, Astrantia, Berzelia, and clubmoss greenery.

Both stamps were arranged by floral designer Carol Caggiano and photographed by Renée Comet. Art director Ethel Kessler designed the stamp.
