This listing contains a 1962 US Geological Survey Map. It is the Antimony in the United States map concerning mineral investigations resource map #MR-20. The map comes with an Explanatory text sheet with the giant map. Although not professionally graded, I believe and the scans show the condition of both the map and sheet to be at least excellent with off-white pages in my opinion. A great buy for a great map book at a reasonable price.
