Show Me Your Porto Server Covers & Other WWII Illustrated Covers!

Over the last few months I have picked up a variety of illustrated WWII covers, but so far the Porto Server covers are my favorite.
However, there does not seem to be any online resource for them! I have no clue about how many designs exist.

If you have any Porto Server covers, or other illustrated covers, please feel free to share them!

Here are mine Porto Server covers:





Uploaded the back aswell because of the sticker.

The image optimizer covered them in dots for some reason, the tank cover is the closet to how they actually look, but with no dots.

The Porto-Server covers are listed in "United States Patriotic Envelopes of World War ll" by Lawrence Sherman and published by James Lee.

eBay sold Porto-Server cachets.

Thanks! I'll have to get that book! Looks like I'm missing at least 4 more after looking at the sold listings.
