I wanted to feature another picture of Thomas Nast. Nast is mostly remembered for his political satire artwork of the late 1800's. He was also responsible for creating our modern image of Santa Claus. The thing I wanted to point out is that he got his start as a war illustrator for Harper's Weekly. I consider him to be the best war illustrator Harper's had, and that is saying a lot, given that Winslow Homer also worked there at the time.
Harper's Weekly published thousands of Civil War illustrations during the conflict, but I consider the absolute best to be "On to Richmond", shown below. Yes, it was done by Thomas Nast. Click on the illustration and look at the incredible detail in the drawing.
