While the format is the same as the Maps of Gettysburg and the Maps of First Bull Run, you will see that the maps in the new book are much more vibrant. The units almost pop off the page...okay, maybe I am being a bit dramatic.
There is also more of an attention to showing where units came from as opposed to them suddenly popping onto a map.
All in all, I am very pleased with the product. I hope you are too! Please let me know what you think.
