1999-2012 Scenic Landscapes #C133-C150

End of an era – our last U.S. airmail stamps! The Scenic American Landscapes were the first and only self-adhesive airmail stamps and their diverse images celebrate the natural beauty of our nation with photographs, often surreal, showing tranquil, majestic settings in a rainbow of colors. National parks from Maine's Acadia to California's Yosemite, from Alaska's Mt. McKinley to Guam's tropical Hagatna Bay, it's a tribute to nature's endless beauty.
