Tim Hartin of Paratime Design is easily my favorite cartographer and has long offered enhanced version of his weekly free maps for $1. The $1 version consisted of a pdf where you could toggle stuff on and off. While nice, they was perhaps less useful than it could be for people who want to use the maps for virtual table tops and such.
So he's going back and including zip files of the raw graphic files for all the maps. Starting with the most recent and going backwards.
