Virginia Commonwealth University Libraries have digitized PS, the US Army's preventive maintenance magazine. From the 1950s through the 1990s they used comics to teach mechanics how to take care of army equipment. For the first twenty years the art director was none other than the legendary cartoonist, Will Eisner, creator of the Spirit, and inspiration for almost everyone in the business. Not surprisingly, a whole lot of top notch cartoonists put in some time at PS.
The lady on the cover, by the way, is named Connie, and contrary to what you might expect, the beautiful blond is the smart character in the comic, keeping the soldiers from screwing up.
