Very nice set of three visually striking color 49.5 x 41 charts titled “Mars Planning Charts,” all three showing areas of the Martian surface. One especially interesting chart features tables of the planet’s physical data and descriptions of the surface, including the polar ice cap. All three originate from the estate of a gentleman who retired as assistant director of The Aeronautical Charts and Information Center. In fine condition, with a few scattered edge creases. Rolled.
