This poster is from the 1864 presidential election. It shows two men, George B. McClellan and George H. Pendleton, running for president and vice president, respectively.
McClellan is depicted in a uniform. He was a war hero of the time, which would have been widely known. The images that surround the two candidates include a harbor crowded with factories, a symbol known as the horn of plenty, and multiple flags.
