Getting ready to play OSG
I always make copies of everything for my own personal use. I scan everything that comes in a box to digits, print it and use it instead of the originals. Here what you need to play a game from the OSG LIBRARY OF NAPOLEONIC BATTLES. All photos from Napoleon Invades Spain (NIS).
The Map (can't copy that) This is a small map from NIS, the Battle of Vimiero.
