I was sorting through some of my boxes of covers and I have a couple that have the N.R.A. logo (National Recovery Act) on them. I have 2 different types but was wondering just how many types of logos exists on covers.
Granted, both these covers are tatty somewhat but they are interesting nonetheless. Both covers appear like one over the other here but they are actually single covers. I don't know why they were done that way?
Probably a correspondence course. In the Depression, everybody and his brother advertised "courses" in radio, aircraft maintenance, and small engine repair. Look at any Popular Mechanics of the early 1930s.
For the record, NRA = National Recovery Administration. The logos referred to on the covers shown are one in the same, the only difference being size and, of course, one is printed in blue and the other in black. The proper logo should have the eagle printed in blue (but black was apparently acceptable when B&W printing was used.) In fact, three color labels were often used, too, with the blue eagle at the center and the words "NRA" and "We Do Our Part" printed in red, all on a white background.
As for the National Radio Institute, as mentioned earlier, they were a correspondence course company founded in 1914. McGraw-Hill purchased them in 1968, renaming it NRI-McGraw Hill Continuing Education Center. In 1999 it was announced they would be phased out due to "changes in the marketplace" and they subsequently ceased operations on March 31, 2002.
(Trivia: The NRA logo was the inspiration for naming the Philadelphia Eagles Football Team.)
