The U.S. Postal Service will begin celebrating the National Park Service’s Aug. 25 centennial just in time for summer vacation letter writing by issuing a pane of stunning Forever stamps depicting 16 examples of our national treasures on June 2.

To create buzz and excitement among national park fans, each stamp will be previewed alphabetically over the next three weeks, beginning today.

“These stamps celebrate the 100th anniversary of the national parks and depict the beauty and diversity of these national treasures,” said Postmaster General Megan J. Brennan. “They serve as an inspiration for Americans to visit, learn and to write cherished memories of their trips to these incredible wonders.”

“This set of stamps will take people on a journey to some of the most amazing places in the world,” said Park Service Director Jonathan B. Jarvis. “We are thrilled that the 16 national park stamps issued in ’16 for the centennial depict the variety of parks that collectively tell the story of our country.”

The June 2 first-day-of-issue ceremony will take place at New York City’s Javits Center at 11 a.m. as part of World Stamp Show NY-2016. Dedication ceremonies also will take place at or near each of the national parks depicted on the stamps. Individuals are asked to spread the news on social media by using the hashtags #FindYourPark or #NPS100.

World Stamp Show NY-2016 will take place May 28-June 4. Held only once a decade, this mega event is not to be missed by beginners through advanced stamp collectors alike. There will be something for everyone there, no matter what you collect. Stamp collecting is a hobby for a lifetime. No matter what your specialty, you’ll find it at the show.

The Postal Service receives no tax dollars for operating expenses and relies on the sale of postage, products and services to fund its operations.
