Eastern National has been a cooperating association member of the National Park Service for well over the past quarter century. Eastern National bookstores can been seen in many National Park Service sites across America, including the Obed Wild and Scenic River. A portion of the sales of Eastern National bookstores goes directly to the parks that they represent, making those parks the beneficiary of the public's contributions for the conservational and educational goals of those parks.
One need not visit a National Park to obtain quality Eastern National merchandise, however. You can check out the Eastern National website at http://www.eParks.com for a variety of books, clothing, etc., from many of the representative parks that you can order online.
