1943 Coca-Cola Aviation Cards

This small package was in a case with many Coke smalls, all of which I was not interested in, but this was flipped face down. I am very happy my curiosity got the best of me. I asked the vendor if he could open the case so I can look at something. I flipped the envelope over and my eyes lit up. A small treasure. The 20 card set is complete and now part of my collection. The price guide doesn't show all the graphics, so here they are folks.
There is one lone card with what I believe is a piece of a puzzle. It is blank on the other side. Looks like a section of what may be a soldiers backpack (?).
