Young Brothers Pharmacy is a popular landmark in Cartersville, and you don't even have to go inside to see why. The outside east wall of the building is said to be the world's first painted outdoor wall advertisement for Coca-Cola. It was painted in 1894 by James Couden. The sign has been authenticated by Coca-Cola and is on the National Register of Historic Places. Inside, Young Brothers has an assortment of Coca-Cola memorabillia for sale, but it is an actual pharmacy where you can have your prescription filled or pick up medical supplies, vitamins, and over-the-counter medications.
