Escape maps were the creation of Clayton Hutton, an eccentric MI9 British Army Officer during WW2. Hutton had maps printed onto silk as they don't degrade in water nor rustle like paper. The maps were issued to the military throughout WW2 and beyond with troops hiding maps inside the lining of their uniform or the heel of their boot. If they were captured or shot down, they had their map for escaping. Perfect gift for a 'silk' wedding anniversary and a great gift for men or women.
