Commemorative issue Transpacific air mail 50th anniversary
Martin M-130 China Clipper
An illustration of one of the famous "China Clipper" flying boat aircraft aptly is used as the basis of a stamp design honoring the 50th anniversary of air mail service between the United States and nations reached by crossing the Pacific Ocean. Development of such long-range aircraft cleared a major hurdle in the rapid transport of mail and passengers to parts of the world heretofore principally accessible from the United States only by ship.
