Keep up the fine work!
I'd suggest you do one for literature, and one for poetry. For lit, you could have an image of War and Peace
, for instance, and then an image of anything by Toni Morrison. For poetry, you could have an image of the collected works of W. B. Yeats (or T. S. Eliot, or Ezra Pound), and then an image of anything by Maya Angelou.
