A picture postcard of the Ely Cathedral with a circular date stamp "Cambridge" of September 7, 1943. This is a very scarce item, possibly written from someone at Cambridge University. Much of the correspondence sent to and from Bletchley Park was destroyed after World War II ended. Part of the correspondence states, ". . . Am very busy with project which is becoming quite exciting . . ." Possibly the Enigma Code?
Front and reverse of postcard.
