Design: Desert River Crossing Size: 36" tall x 36" wide Material: Commercial Grade Artist Canvas About Ravenwood Game's Battle Mats We don?t just work ? sometimes we play and when we do its old school tabletop games. With a long history of gaming back to the 1980s we've picked up some insight into what makes a good map and we incorporate it into all our Battle Mats. The scale for our maps is 28mm, the most common scale, but of course if a map looks suitable for your unique scale there's no reason you can't use it. Grid Options All our Battle Mats are available with optional 1" grids or hexes printed directly on the map. Standard option is plain with no markings. If you would like a grid or hex please message me immediately after you order. If no grid is requested you will receive a gridless map.
