A friend of mine is a comic book collector and no minor authority on the subject as a whole. Last summer he asked me to take some snaps of three panels of original art from Our Army At War, a comic book anthology series that ran from 1952 to 1977.
The three pics below are from issue 133, published in August of 1963, and feature the fine artwork of Joe Kubert (and the story script of Robert Kanigher).
From top to bottom: pages 11, 12, 13.
As of this writing, these panels are on auction. ("Six thousand dollars?! I'm in the wrong business.")
