(WY.) Wyoming, State Highawy Dept., 1952 A mid-century gem of a map, done in a color shaded-relief style that beautifully conveys the drama of the topography. Cultural features are clearly marked from roads and towns, to the new "Official Air Lanes" as they stretch from major town to town. Condition is very good.
