This 21.75"x33" poster map depicts the Inner Sea Region of the Pathfinder Campaign Setting. This is the same map that is included in the Pathfinder Campaign Setting: Inner Sea World Guide. It is shipped flat, folded to approximately 8.25"x11".
If you're looking for the ultimate map of the Inner Sea Region, you'll want to consider the Pathfinder Campaign Setting: Inner Sea Poster Map Folio, which is four times larger than this map, and includes labels for many more locations.
Just for the record: its 1 inch longer than the map in the original (3.5) campaign guide, but otherwise similar in size. (Got my new campaign guide today)
The colour contrast has been improved, and the wording is a lot bigger and clearer. The borders are also clearer. (One early PC was from Ostenso, in Andoran... in the campaign I was playing in)
It's certainly a better map, but if you have the original map, I am not convinced its worth the extra money to buy it seperatly.
If you want a nice big map, and don't want the campaign guide, or the even bigger map, its a good product.
Well I am two minds about the lost cities on the map. As a GM I like it for reference. But I get Osopolare's point. I don't recall off the top of my head if the latest gaz map had them listed or not. If not then it is a good player map and this a good GM map.
