Rare WW2 British Nazi POW Camp map

Very rare WW2 German POW prisoners of war camp blue prints / map.  Eselheide was  POW camp in Germany which mainly held Russian prisoners of war up until 1945 when the British liberated the camp and released all the Russian soldiers and was then turned into temperary British internment Camp which held high ranking German Officers and government officials as they awaited trial for war crimes. Extremely rare I have never seen another one anywhere. Also comes with a RAF translation book that was found together and given to Germans while in British custody ?.
