Hello, I hope you enjoy seeing this cover. Flown Manila to San Francisco in 1935 on the return legs of the first transpacific flight. A significant achievement in aviation back then.
This was Pan Am’s Martin M-130 flying boat, better known as the China Clipper.
The cover shows the special stamps issued by the Philippines Post Office; the 10c Fort Santiago stamp and the 30c Blood Compact issue with overprint PI – US Initial Flight December 1935.
There was a special cachet, as shown on the left hand side of the cover, for mail carried on the flight from Manila to San Francisco, and this was on 74,719 pieces of mail.
Enjoy your flying and your stamps. Michael cddstamps.com
