Sc. 5080e National Parks on a 5"x7" Dragon Card showing a sign similar to those that might be found at the entrance to a National Park. The sign reads "National Park Service Centennial." The Grand Canyon single and the GC stamp from the Celebrate the Century series (3183h) are tied by the B&W first-day postmark. Great for a parks- or conservation-on-stamps collection!
