Day twelve brings us these beautiful stamps! This series is called the Earthscape series. It will actually feature 15 stamps total, but the USPS is choosing to reveal 5 at a time. I don't know about you, but I cannot wait to see the rest!
The photos used on the stamps were created by either taking photos from the "Eyes in the sky" (satellites) or by a photographer from some sort of aircraft. Which is why they didn't actually list the illustrators for this series. =)
