From the front cover:
Welcome to the Ptolus Deluxe Map Pack. Inside you will find eighty maps originally appearing in Ptolus: Monte Cook’s City by the Spire. Each map is presented as a full page image for easy reference and includes the original labeled version and a version with most of the labels removed. Only title, scale, and compass have been left on the unlabeled maps. Each map references the chapter and page number in Ptolus: Monte Cook’s City by the Spire so you can find the information you need quickly during game play. Perfect as a GM utility or as player handouts, these maps will be a welcome addition to any Ptolus campaign.
