The above map, published in July 1863 and certainly one of the first to show West Virginia as a separate state, is beautiful all by itself, but Harvard Law School Library ups the cool factor even more. It has a fragment of a copy that once belonged to Oliver Wendell Holmes, who owned the map while fighting in Virginia during the Civil War.
The inscription in the bottom-right corner, in Holmes’s hand, reads: “I carried this in the spring campaign 1864 from Brandy Sta. to Petersburg—Gen. Grant took it for a moment at Spotsylvania & looked at it”
