On August 1, 1928, air mail rates were reduced from 10-cents per half ounce to 5-cents for one ounce. That was a huge reduction and was heavily promoted. This cover is an example of those promotional efforts.
I'm curious about the cachet. I've searched online and can find plenty of information about the Fairchild FC-2 as a mail plane. I can't find any news stories, however, about the Fairchild FC-2, which had foldable wings, directly picking up mail from a post office.
Suppose that never happened and this was just one more gimmick to promote air mail in the 1920s?
