Show your airmail covers with different borders

As promised in a recent post in Aircraft on Covers, I am beginning a thread on variant airmail borders on covers.  I began collecting these covers in the late 1990s without realizing its scope and the number of different airmail border designs there are.  It is a large collecting field with very few collectors.  In the 20 + years I have been collecting these covers I have encountered only five other collectors.  I estimate that I have accumulated around 300 different such covers and still find new ones regularly. 

Perhaps, the quickest and easiest way to introduce this collecting field to others is to post a link to a site created by R. Courtney a pioneer collector of these airmail covers.
rhcourtney-collector.com/Airmailenvelopes.html   Click on the link and then scroll down to an image entitled United States Airmail Envelopes from the 1920s to the 1960s and click on the image. That will go to an introduction and a visual presentation of many of these covers. One of the most interesting aspects of Courtney's site is his showing of the covers without their stamps, cachets, and other markings. This allows the viewer to focus on the design of the envelope. When I have shown these covers at stamp club meetings, one of the most frequent remarks I receive is "I never noticed these covers before." That is they have seen the covers only for the philatelic attributes that are displayed on them. The border airmail designations are only background.

My attempts to show these covers on other forums have been met with a lot of yawns and moving onto other threads. Never-the-less, I continue to be remain a steadfast collector of these covers. Below is the first cover I collected specifically for its border. I purchased it at an annual stamp show in Oklahoma City. It was in a dealer's $1 box. I was attracted to the arrows and asked the dealer if there were others like this. He didn't really know, nor did he know if anyone collected covers for their airmail borders. He did, however, make a convert that day.

The cover below is unusual in that its designer and distributor is known.  It is a Stouzenberg cover.  J.W. Stouzenberg was a printer and cachet designer from Maplewood, Missouri, who printed five different airmail borders on envelopes.  I know this because he printed his name and address on back of his covers.  The designers of most of the envelopes with variant airmail borders are unknown, however.  Some were collectors or cover dealers who created their own designs, others were commercial in origin and sold to the general public, some were created by philatelic organizations.   

I have grouped these covers into 20 different categories of similar designs.  I will show initially one from each category and then move on to those that I find more dramatic or interesting.  Undoubtedly, airmail cover collectors have covers with variant borders.  Please show what you have.  My collection is far from all inclusive and I'm always interested in seeing borders with different designs and from different time periods.
