This military map is one of a series printed during ww2 for Italian forces.
Originally printed for the invasion of Eygpt (operazione E) and throughout their campaign in North Africa.
The maps in this series , were essentially stolen data copied directly from other nations maps of the area. This was mainly british maps, from outdated series such as the 1918 and 1930 war office surveys.
The addition of Riservata (mod12) to the top corner is the only difference between the "new" Italian maps and the earlier British map that it is copied from.
