U.S. Stamp Notes by John M. Hotchner
In 1946, the United States Post Office Department began to use a design featuring the DC-4 Skymaster on a carmine background for its workhorse stamps paying domestic airmail letter rates.
Ultimately three sheet stamps were issued showing this transport plane: the 1946 large-format 5¢ (Scott C32), 1947 small-format 5¢ (C33) and 1949 6¢ (C39), all shown in Figure 1. There also was a coil version of the small-format 5¢ issued in 1948 (C37) and coil and booklet versions of the 1949 6¢ (C41 and C39a, respectively).
Bureau of Engraving and Printing designer Victor S. McCloskey Jr. designed the vignettes for these stamps.
Two countries, Liberia and the Philippines, modeled airmail designs principally used on aerograms on this U.S. stamp design.
Four Liberian usages of the design from 1948 to 1964 are shown with this column. Three of them are handstamped, while I believe the example shown in Figure 2 is printed on the aerogram.
However this example, canceled Dec. 7, 1948, is not a true imitation of the U.S. stamp and is not even in the correct carmine color.
While the example on the 1949 cover shown in Figure 3 is closer to the correct color, it also is not faithful to the U.S. stamp design. This example is denominated 12¢, while the other three are all denominated 10¢.
The design on the aerogram in Figure 4 more closely resembles the U.S. stamp. This aerogram was used in 1950.
The handstamps are of varying levels of quality. Figure 5 pictures an example used in 1964 with a somewhat muddy appearance.
I don’t know when these designs were introduced in Liberia or how long they lasted.
What I do know is that the handstamps were applied prior to or as the mailed items were sold because I have one unaddressed and uncanceled business-size envelope with a 25¢ version of the design.
The Philippines used the printed variant on aerograms starting in at least 1948. Two versions are known to me: red on blue paper, and blue on pink paper, as shown in Figure 6. These are interesting because the airplane is facing left unlike the original U.S. stamps. Perhaps this was the Philippines’ way of marking the stamps as its own rather than simply copying the original design.
The Philippines examples clearly state the name of the country. This is not so with the Liberian cousins. Each of those contains the letters R.L. for Republic of Liberia somewhere in the design.
Note that all of the examples use images of perforations as part of the design as a means of giving the printed or handstamped indicia the look of postage stamps.
