This is a rather unique Map. It is from 1957 and is actually an "Index To Topographic Mapping in Montana". It has areas blocked off across Montana..i.e...LIBBY.....THOMPSON LAKES...STTRYKER....KINTLA LAKES and so on. Really different...they probably made topographic maps for each of these areas. Interesting to see Montana blocked off like that...it easy to read and see. A nice old collectible. Price $ 18.00.
