Adam did a fantastic job on this map. He says that he sees some text that is different sizes, but that just makes it more "hand written" than computer drawn in my opinion. If you are looking for the original TIF files that he provided, you can look at the second post on page 1 of this post and you will see where you can download the color, black and white and sepia files that he provided.
Thank you again for all your hard work on this and for posting this Adam.
