He wanted a map that was strong, silent to use, lightweight and easy to conceal. By using wood pulp from the Mulberry tree this goal was achieved and the resulting maps are incredibly thin and light. They could be screwed up almost silently, soaked in water and yet still used. Due to the lack of bulk they could also be concealed in much smaller spaces than the equivalent silk map. This example is in very good condition, unfolded, crease free and aside from minor folded corners and a very small hole, unblemished. Stock code E26849.
