Set of three first edition Lunar Module Ascent and Descent Monitoring Charts for the Apollo 11 mission, each dated June 1969, and showing the lunar terrain flight path for landing site No. 3. The charts include: an LM Descent Monitoring Chart, 21 x 10, sheet 1 of 4; an LM Descent Monitoring Chart, 35.75 x 12.5, sheet 3A; and an LM Ascent Monitoring Chart, sheet 3B. The charts are lithographed by ACIC 6-69 and 7-69, and prepared under the direction of the Department of Defense by the Aeronautical Chart and Information Center. Rolled and in overall very good to fine condition, with scattered light creasing, and folds to the larger charts. Alternate 'Landing Site 3' was deemed Sinus Medii or 'Bay of the Center,' due it being at the intersection of the lunar equator and prime meridian; a launch delay of two days would have made it the Apollo 11 landing spot as it would have been receiving more sunlight.
