This Apollo star chart (Northern Hemisphere) comes from the personal collection of Walt Cunningham, and was used in astronavigation training during preparation for Apollo 7.  

The chart is printed on Chronopaque (a special flight-approved film developed by DuPont Corporation that met NASA's stringent fire and outgassing specifications), and shows a Northern polar projection of the constellations, stars, and planets.  Star charts such as this one were produced in very limited quantities and were used exclusively for crew training, mission planning, and flight operations. 
 
Included is a copy of Cunningham's COA for this item, as well as an original COA from Don Willis of Lunar Legacies who sold this on behalf of Walt Cunningham.  If the buyer purchases both Northern and Southern Hemisphere charts, the original Cunningham COA (which authenticates both charts in a single COA) will be included in place of the copy.
