 This is actually the cover of a piece of sheet music that was published in 1864 in New York. This is the American Petroleum Polka, or Chottischer Gallup or Waltzer March. And it has a picture of a beautiful Pennsylvania scene. The oil well spouting its oil. Now, oil was black back then, oil is still black, but you couldn't have black oil falling on the ladies pink dress, so they made the oil white. And they're bragging. This oil well threw pure oil a hundred feet high. People understood the value that you get from oil, from petroleum, and they celebrated that.
