The Complete Gettysburg Guide book has a Facebook page.
Here's the link.
Here's a map posted there. Looks clear and sharp. CWL likes: the clock in the upper right hand corner, the 1863 fence lines, wood lines, and farm buildings. The scale is marked in 500 and 1000 feet and that's a nice feature to use at home. Quibble: the Wentz house is not show but it is in the middle of the 2nd New Hampshire's line, showing and labeling the house might clutter the map; but on the other hand the Staub house is shown and it is usually left off most other books' maps. There are 70 maps like in The Complete Gettysburg Guide.
When taking anniversary tours of the battlefield with NPS rangers CWL 's cargo pants' pockets carry the Friend's Maps, McElfresh Watercolor Maps and the Trailhead map. Hopefully The Complete Gettysburg Guide will fit in the wide side pockets, because it looks like it will be travelling on the battlefield with me.
