To celebrate the 100th anniversary of the National Park Service, there is a new series of U.S. stamps that feature the National Parks. The third of sixteen stamps celebrates the wild ponies Assateague, which can be seen above.

Tim Fitzharris from Arkansas photographed the image for the stamp. Here is his website: http://www.timfitzharris.com

These wild ponies are immortalized in the book by Marguerite Henry, Misty of Chincoteague along with many of her other books. The Assateague State Park that the wild horses reside on is by Virginia-Maryland border, is known for the horses that inhabit the island and the nearby Chincoteague National Wildlife Refuge. The horses are divided into two herds — one on the Virginia side of a fence marking the state border, the other on the Maryland side.

The stamps will be issued out on June 2nd, 2016.
