The map is pretty much what you expect of a UK touring map coloured to indicate heights (green - brown), but with the modern road information all changed to a light grey to make it less obtrusive. Roman sites are then marked in coloured symbols and words. The map is double sided with the South on one side and the North on the other, split near Kendal
The quantity of Roman information in this map is many times greater than that in the "Ancient Britain" Map, and is much clearer by virtue of the colours used. The network of Roman roads are marked in red and clearly indicate towns and cities, although many of the marked sites seem to be away from obvious roads.
It would probably better suit electronic publishing, where you could choose to switch on and off different information, to give you clearer views of what you want.
For studying Roman Britain, I think this would be a good place to start. If you need it on a wall, then buy two copies.
