Poster showing the flag and the United States Capitol, with a message from Woodrow Wilson.
Caption: To the miner let me say that he stands where the farmer does; the work of the world waits on him. If he slacks or fails armies and statesmen are helpless. He also is enlisted in the great service army. Woodrow Wilson.
