Some war comics by N.C. Wyeth.
I’m thinking these were done by an artist emulating Wyeth’s style. He died in 1945 and these comics look like they were from the 1950s or later. The comic book code shown on these covers was not created till 1954.
After doing some research, you are partially correct. I believe that N.C. Wyeth painted these, but they were never used as published comic book covers. If anyone has more information, please message me!
