It seems that the “National –insert cause here– Week” concept has been around for much longer than I thought.
At its introduction, one had to pay a premium for air mail service (24 cents) compared to regular first-class mail (3 cents). With the serious occupational hazards the first air mail pilots endured, I think the price was justified.
According to Edward A. Keogh, 1927, the earliest Air Mail service in the United States carried many more postcards than other type of mail, by a landslide, though the dates over which this tally was amassed is unclear.
Though postcards are becoming rarer, we are now more dependent on air transport of mail than ever. How could we get our online purchases “over-nighted” without our packages continuing to take to the sky?
Side note: Philately is far too competitive for my taste, but I recently learned more about the famous “Inverted Jenny” stamp, the holy grail of stamp collectors valued at about $1 million. The stamp came about because of the rush to produce the 24 cent air mail postage. I much prefer the humanity that is revealed on vintage send postcards, but it’s also a hobby that’s much easier on the wallet than stamp collecting.
