Iconic Assateague wild horses feature on new US postage stamp

The iconic wild horses that inhabit Assateague Island National Seashore will feature in a stamp series celebrating the 100th anniversary of the US National Park Service.
Assateague Island National Seashore is a national park that straddles Maryland and Virginia. It is home to a famous herd of wild horses, immortalized in Marguerite Henry’s children’s book, Misty of Chincoteague.
Horses in the park feature in the third of 16 stamps being revealed over three weeks to mark the agency’s anniversary.
A photograph by Tim Fitzharris, of Fayetteville, Arkansas, was used to create the stamp.
This barrier island is made up of sandy beaches, salt marshes, maritime forests and coastal bays.
Bands of wild horses freely roam among plants and native animals that have adapted to a life of sand, salt and wind.
Other national park stamps previewed to date include Acadia National Park and Arches National Park.
What I really want to know is how to pronounce Assateague and Chincoteague. So if anyone can come up with a phonetic spelling that answer a 40 year old question.
Ass-a-teeg (short a’s)
Shink-a-teeg
Hello,
When will the Assateague stamp be released.
