1860s Presidential Poster

We don't have the most elaborate story here. We found this little poster on LetGo. It has some water damage (completely dry and the detail of the piece is fantastic). I met the seller at a Dunkin Donuts, where only I had coffee because he didn't like coffee (I would die), and I purchased this piece.  I love traveling the world but I am a proud American. So when I see some cool Americana, I always jump on it. This is very early, in a very old frame, with some very important people featured. Everything on the poster is clearly hand drawn art that was most likely plate printed on to the paper.  Dimensions: 16” H x 12” W x 1” D
