Just popping in with an illustration before I fall into a snowdrift (or is that big, white hillock just a pile of comics pages?).
This is an unused illustration for the Ballad of the White Horse, by G.K. Chesterton. It shows Alfred watching the Danes arrive in England.

Also, artist Daniel Mitsu posted a pretty amazing drawing on vellum over on the SmallPax blog. Be sure to take a look at the amazing detail.
