9 of the stamps can be seen on this lovely cover sent from Virginia, USA. The 10th stamp belongs to the Mount Rushmore Priority Mail stamp with a denomination of US$4.80, issued on 6th June 2008. This Priority Mail stamp features an illustration of Mount Rushmore National Memorial, which is located in the Black Hills of South Dakota near the town of Keystone. Carved into Mt Rushmore itself, the monument consists of large-scale sculptures of the faces of four American presidents: George Washington, Thomas Jefferson, Abraham Lincoln, and Theodore Roosevelt.
I would love to visit this awe-inspiring monument one day!
