During World War II, the Union Pacific recruited the Willmarths to create a series of morale-boosting posters. Some on-line sources date a few of these posters as early as 1940, but this seems unlikely as the U.S. did not enter the war until the end of 1941. Other posters are dated 1944 which seems more reasonable.

The engineer in this image is supposed to look determined, but virtually the same face could be put on a poster warning of enemies within.
Unfortunately, I wasn’t able to find larger images of the above poster or any of the three below.
The rivet-counting level of detail in the posters above and below suggest that most time was devoted to the painting and possibly that Kenneth Willmarth was more involved in the work than William.

The light-hearted nature of the poster below suggests is was done near the end of the war when victory was in sight.
