©2014 USPS

On March 21, 2014, in Saint Louis Missouri, the U.S. Postal Service will issue the Yes, I Do 70-cent definitive stamp, in one design in a pressure-sensitive adhesive (PSA) pane of 20 stamps (Item 587600).

The stamp will go on sale nationwide March 21, 2014.

The U.S. Postal Service continues its celebration of weddings with its most recent addition to the popular Weddings series, the Yes, I Do stamp, first issued in 2013. Sold at the two-ounce stamp rate, Yes, I Do accommodates the heavier weight of an invitation, as well as other mailings such as oversized cards or small gifts that require extra postage. The stamp highlights the words ìYes, I Doî nestled in a bouquet of flowers in the shape of a heart on a white background. A similarly designed companion stamp, Where Dreams Blossom’a Forever stamp first issued in 2013’is available for response cards, save-the-date notices, thank-you notes, and other correspondence. The stamp artwork was designed by Michael Osborne under the direction of Ethel Kessler.
