WASHINGTON — Wild horses of Maryland’s and Virginia’s Assateague Island National Seashore were previewed this week as the third of 16 Forever Stamp images to celebrate the National Park Service’s 100th anniversary.

A photograph by Tim Fitzharris of Fayetteville, Ark., was used to create the image.

A press release from the United States Postal Service reported, “This barrier island is a tale of constant movement and change. Explore sandy beaches, salt marshes, maritime forests and coastal bays. Bands of wild horses freely roam amongst plants and native animals that have adapted to a life of sand, salt and wind.”

The June 2 first-day-of-issue ceremony for the National Parks Forever Stamps pane will take place at New York City’s Javits Center as part of the World Stamp Show. Dedication ceremonies also will take place at or near each of the National Parks depicted on the stamps.

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