So if I were to guess who would invent an imaginary island dictatorship, with a history, leadership, armed forces and order of battle and make a set of meticulously detailed maps of the place, IN ESPERANTO, I would have expected it to be a Dungeon Master. I would NOT have expected an NSA crypyanalyst and world famous virtuoso flautist. Learn something every day in this biz. Do yourself a favor and Google Lambros Demetrios Callimahos. This guy was amazing. These maps were material for Callimahos' secret NSA cryptanalysis course which ran for 22 years to 12 students at a time. It must have been a hell of a class. We see these in no institutional collections in oclc, and we know of no other examples to ever be offered for sale. #raremaps #geographicusantiquemaps #li #nsa #cryptanalysis #esperanto #zendiaproblem #mykindofgeek (at Geographicus Rare Antique Maps) https://www.instagram.com/p/B_GVJLGJDCa/?igshid=lr0defbu61wv
