From publisher blurb:
Into the Wilderness: Map 0 is a map-pack by Crooked Staff Publishing that not only lets you check out the art style of the maps provided in other Into the Wilderness products (i.e. allowing you to 'try before you buy'), but also provides you with a handy forest map that can be used in either a VTT (virtual tabletop) or a regular tabletop environment.
As such, this product includes:
A pdf booklet containing a (single page) GM version of the map, as well as a (six page) miniatures-scale battlemap version.
A separate image file optimised for use with virtual tabletops (VTTs).
It is also worth noting that this particular map has been designed with a repeating forest pattern - so that you can connect additional copies of the map together seamlessly (or use the 'tile image' option in your VTT software) to create a truly massive area for your players to explore.
