The Postal Service issued the 84-cent International Polar Year 2007-2008 stamps on February 21, 2007, in Fairbanks, Alaska.
Continuing the tradition of international cooperation that began with the first International Polar Year (IPY) in 1882-1883, scientists from around the world initiated a new era in polar research by participating in IPY 2007-2008. Working across many disciplines, the scientists conducted field observations, research, and analysis to build upon current knowledge and increase our understanding of the roles that both polar regions play in global processes.
The two stamp designs by Phil Jordan of Falls Church, Virginia, are based on two photographs. The photograph of the Aurora Borealis, or "northern lights," was made by Fred Hirschmann of Wasilla, Alaska. The photograph of the Aurora Australis, a phenomenon of the southern polar region, was made by Per-Andre Hoffmann of Stuttgart, Germany.
Ashton-Potter (USA), Ltd., produced 4 billion stamps in the offset process with microprint "USPS".
