This blog post is linking to a story about the circumstances surrounding the Zimmermann telegram. So, for the image you create, make it look like an authentic historical photo with the telegram within the scene. The photo should look like something from 1917 or thereabouts. Have the telegram sitting on a desk in the foreground with British intelligence discussing it with a US embassy official.
