That is fantastic. Didn't know the Linprint connection and wouldn't have unless I soaked the stamps off.

Hello.
I'm missing one to complete the series.
When I get it, I'll ride it with the envelope.
Regards.

I was 10-12 years old when an uncle gave me a box of covers, including this one. Cancel is from Pearl Harbor, November 3, 1940.

Wikipedia has an excellent history of the USS William B. Preston's exploits in the Pacific theatre during WWII.

Here are a few more. All have blank backsides.

Hey folks, While this topic is a bit restrictive go over to world covers to post anything non-US. If you have a unique take on the barber pole border please post.

A couple from my wife's AZ postmark collection. Sadly, the USS Arizona was lost just a few months later on December 7, 1941.

One last one...

planes in the envelope design are a favorite of mine.

Anyone know the designer/manufacturer of this design? I have 13 variations so far. One source said Harry Ioor.

Here's an unconventional Esperanto-themed one with a hand-lettered border:

erilaz, I like that Esperanto border!

The airlines did a few special airmail borders, from my experience mostly in the 1950s and 1960s. TWA's usually incorporated cities it served. Here are a couple of examples.

Some repeating phrase borders. Some attributed to Harry Ioor but fonts and designs were frequently copied.

Stars, an occasionally seen border.
