Description: This item is a specialized cinderella poster stamp produced to honor Australia's expanding geographic and scientific presence in the polar regions. Lithographed in a deep forest green ink on off-white paper stock, the horizontal composition features a single-engine monoplane outfitted with landing skis instead of traditional wheels, cruising low over an expansive landscape of jagged glacial peaks and ice formations. Below the aircraft, a small outpost campsite with radio masts or survey equipment can be seen nestled at the base of the mountains. The top margin is dominated by a bold, stylized title banner reading "ANTARCTICA", which is balanced perfectly across the bottom margin by the identifying text banner "1954 EXPEDITION".
Circa: This commemorative promotional label was officially designed, printed, and distributed to collectors in 1954.
Condition: Unused - Hinged
Notes:
This issue is a classic example of a Cinderella stamp, meaning it was produced by a private source rather than a government entity and carried no valid postal denomination for mailing letters. It was created by the renowned Australian philatelic dealer Bill Hornadge for his firm, Seven Seas Stamps, to celebrate the departure of the historic January 1954 voyage that established Mawson Station; the first permanent Australian research base on the Antarctic continent. Hornadge's promotional campaign originally featured a set of four distinct designs, including this green ski-plane layout, purple penguins, a yellow map, and a red expedition ship. Because these labels were often affixed to the backs of envelopes or special souvenir cards sent down on the actual expedition ship, finding examples on intact envelopes carrying genuine, historical Mawson Station postmarks represents a highly prized trophy for polar postal history enthusiasts.
