I was a child in Manila in 1935 when the Pan American Clipper made its first flight. I have a photo of myself, brother, and mother in the Clipper in Manila Bay. My father sent a letter to his brother in Rochester NY on the return flight. I discovered the envelope last week while visiting my brother, and have scanned it. The envelope is stamped "CHINA CLIPPER - First Flight from MANILA". Stamps were cancelled on Dec 2, 1935 and the enveloped stamped on the reverse side as received in San Francisco on Dec 6, 1935. A map shows that the plane stops at Wake, Midway, and Hawaii on the way to San Francisco.
This envelope and stamps should stir some interest.
