First Day of Issue Ceremony: Stamp Encore

To celebrate 250 years of postal delivery in 2025, the Postal Service introduced “Stamp Encore,” an invitation to the public to choose one stamp to be reprinted from among the 25 most popular stamps of the past three decades. Decided by more than 500,000 votes, the public’s selection will be revealed at a first-day-of-issue ceremony on Sunday, May 24, 2026, the second day of the Boston 2026 World Expo. Since the beginning of the year, an envelope carrying the mysterious Stamp Encore winner has traveled from one first-day ceremony to another. Lisa Bobb-Semple, USPS director of stamp services, says, “Holding a first-day ceremony for this issuance at the Boston expo adds a fun new twist to an already special event.”
