The U.S. Postal Service released its new Diagonal U.S. Flag Forever stamped envelope this month at BALPEX, the annual stamp show hosted by the Baltimore Philatelic Society — one of the oldest stamp-collecting organizations in the country, founded in 1889. This year marked the society’s 88th annual show, held at the BWI Marriott in Linthicum Heights, and it came with an unusual pairing: BALPEX joined forces with Americover, the convention of the American First Day Cover Society, after that group’s usual partner event, the Great American Stamp Show, sat out 2026 to avoid conflicting with the Boston 2026 World Stamp Show.
The envelope itself takes a different approach to a familiar subject. Rather than showing the full flag, the design crops in tight on a diagonal slice of it — five red stripes and four white ones running at an angle across the right side of the image, with a corner of the blue field and 23 white stars visible in the upper left. “USA” and “FOREVER” appear in black lettering at the bottom.
Bryan Duefrene, a senior stamp development specialist at USPS, designed the image. “I was looking for a bolder, eye-catching way of portraying the flag, and decided to focus on the elements of the Stars and Stripes rather than the flag as a whole,” Duefrene said. “I experimented with different crops of the flag before finally landing on the tilted crop you see on the envelope. I think it turned out really well.”
The flag has been a recurring subject for U.S. postage for decades, and its own design history is more complicated than the finished product suggests. The Second Continental Congress passed the first Flag Act in 1777, specifying 13 stripes and 13 stars to represent the original colonies. A second Flag Act in 1794 bumped that to 15 stars and 15 stripes after Vermont and Kentucky joined the union — the version that flew over Fort McHenry during the War of 1812. By 1818, with 20 states in the union and more on the way, Congress settled the design logic still in use today: stripes locked permanently at 13, with one star added for each new state on the July 4 following its admission. The flag hasn’t changed since 1960, when a 50th star was added following Hawaii’s statehood the previous August.
Patriotic themes have shown up on stamped envelopes with some regularity in recent years, including a 2020 design featuring the flag bordered by gold stars and a 2013 issue depicting an eagle carrying twin flags and a shield. The new diagonal design joins that lineage as a Forever product, meaning its postage value automatically tracks whatever the current stamped-envelope rate is at the time it’s used — a detail with real financial weight this year. USPS raised the price of a First-Class Forever stamp to 82 cents in July, part of a broader round of increases the agency has pursued while working through significant financial losses. Anyone holding onto envelopes bought before that increase doesn’t need to add postage; the Forever guarantee covers the difference automatically.
The Diagonal U.S. Flag stamped envelope is available now at Post Offices and on usps.com, and USPS is promoting the release with the hashtag #DiagonalFlagStampedEnvelope.
