On August 28, 2007, in Estes Park, Colorado, the Postal Service issued a commemorative sheet of the 41-cent Alpine Tundra stamps in ten designs. Ethel Kessler of Bethesda, Maryland, designed the stamps, the ninth in the Nature of America Series designed to promote appreciation of major plant and animal communities in the United States.
To illustrate the diversity of species associated with the alpine tundra, artist John D. Dawson of Hilo, Hawaii, depicted more than twenty-four animal and plant species in his beautiful acrylic painting. The scene itself is imaginary. Such a dense grouping of plants and animals was necessary to illustrate as many species as possible on the stamp pane. Even so, all of the species exist on the alpine tundra of Rocky Mountain National Park. All were recommended by scientists.
A description of alpine tundra and a numbered key to the artwork appear on the back of the pane, along with a corresponding list of common and scientific names for twenty-four species.
Sennett Security Products/Banknote Corporation of America, Inc., printed 50 million stamps in the offset process.
