Another favorite today, Clipper covers with variant airmail borders of U.S. Navy ships. I have tried without much success to find our who designed and produced these attractive covers. As the last cover, an unused example, indicates that variety was sold by a "news" company in San Pedro, California, the home port for many Navy ships at that time. It is, however, a slightly different design than the first two shown. Since these covers carry a premium, I am reluctant to remove the stamps to see if the others have a different source.
Another puzzle is that I usually see these covers posted aboard capital ships, i.e. battleships or cruisers. My only exception is the cover posted in Honolulu and there is an accompanying letter with it indicating the writer was stationed aboard
USS Nashville, a cruiser.
Another puzzle is I have not seen examples of this cover posted later than 1940.
If anyone has any information about the origin of these covers, I would appreciate seeing it.

The basic design posted aboard
USS West Virginia
The same design posted in Honolulu

A variation on the border with red & blue rectangles above & below the ships and scroll work in the corners, posted aboard
USS Tennessee.. The rectangles continue on the reverse.

An unused example of the rectangles and scroll work border with the distributor's address in the upper right corner.
