With a Typed Letter Signed by EUGENE CERNAN, stating the importance of the cue cards in the mission. "This LM cue card," he writes, "has remained a treasured part of my personal collection for more than thirty-five years, ever since NASA presented in back to me in 1969, shortly after my return to Earth. This complete Lunar Module Communications Cue Card remains both a historic tool from one of the manned lunar voyages, and a rare example of an astronaut flight-certified artefact returned from the Moon."   

These cue cards were of great importance during the Apollo 10 mission.  Eugene "Gene" Cernan positioned his near the communications console on his side of the spacecraft. The reserve side of the cue card provided a visual reference for the steerable antenna gimbal functions that allowed the lunar module antenna to lock onto radio from the Manned Spaceflight Network on Earth and connected the astronauts directly to Mission Control. This particular cue card remained a treasured part of Cernan's personal space collection for more than 35 years.
