Continuing my research into Napoleon Hill, I came across a remarkable thing in an issue of American Stationer and Office Outfitter:
Prospectus of United Bookstores Co.
The following prospects, printed on a page leaflet, has been sent out by the United Bookstores Co. of America:
An opportunity is presented to a limited number of persons interested in wider and more profitable book distribution to participate in a strictly business enterprise for this purpose by becoming members of a syndicate to promote the United Bookstores Company of America.
From 1921 issues of Flying (click to enlarge):
Designed as a cross between a houseboat and plane, the Caproni Triplane flying boat was one of the largest seaplanes ever built. The plane used three sets of triplane wings taken from World War I bombers attached to a 100-passenger flying boat hull. Powered by eight 400-hp engines, the plan was to carry 100 passengers as well as six pilots and flight engineers. However, on the plane’s second flight in 1921, it crashed into a lake, killing both pilots, which led designers to scrap the design.
Still, it must have been something to see in person!

The term “snail mail” appears as early as 1942 in the headline of a news article about slow mail delivery. The term also appears as a sub-headline in a 1951 news article.
