Pluto Disney Military Air Force Insignia Artwork, Vintage WW2 Airbrush Original Art

This is a vintage original airbrush art work for an air force / military battalion. I wish I knew more about it. It was purchased at an estate sale and it was framed and sealed on the back when I bought it. I opened it up to see what it was painted on etc. It is airbrushed on a thin piece of cardboard that measures about 10" x 9.5", frame is slightly bigger (you can see the back of the piece its on in the third picture, its the 3rd piece).

There are 2 lines that cross through center from top to bottom and side to side like it was folded at one time, but didn't look to have been on the back. I find no signature or dates. The frame looks to be older to me as does the art and from what I understand most of this stuff was done during world war two. It is being sold as-is for what it is. I can ship it with the frame or with out, just let me know which you prefer.
