The University of the South has digitized the Polk Family Papers. While going there to find something related to Shiloh (there was not much but it’s a hard site to use) I came upon a comic strip titled Under the Stars and Bars. It depicts the battle of Belmont in its final phase and was published in The Nashville Banner. It is not too surprising. The paper did full print runs with original art for many Civil War battles for the centennial. I looked through the one on the battle of Nashville, which is digitized by the Battle of Nashville Trust. I hoped to use some images in my upcoming book on the subject. Alas, they wanted a lot of money per image and being part of a massive media conglomerate, they are not as forgiving as a research center or library sometimes can be.
If anyone recalls reading this or knows were to get the full run I would be interested. Below are images of Belmont and a link to where I found it. The images as I could save them on my computer are not of the highest quality, but do give a feel for the style. Leonidas Polk in particular is well drawn.
