A jokey map of Frankfurt drawn by SSGT "Lederhosen Lefty" Burgess in 1954 with a lot of GI humor (e.g. it shows not only a HiCoG but also a MiddleCog and a LowCoG). It includes an amazing amount of detail and I learned some things from it; for example, did you ever wonder why the circle at the intersection of Adickes Allee and Eschersheimer Landstraße was called WAC Circle? Because a WAC barracks used to be there. The map was printed by the Stars and Stripes and sold for 50¢.
