This important mission was a prelude to the lunar landing during a number of programs were tested for the first time, including the CSM/LM operations in cislunar (atomospheric region between Earth and the Moon) and lunar environment and a simulated lunar landing. Large lunar presentation photo, 14"x10¾", laid to mat. Overall 18½"x15½". Inscribed at top mount: "To Bill Dana - our fourth crew member...Wish you could have joined us instead of staying on the launch pad." Boldly signed at bottom mat by TOM STAFFORD (b. 1930); and future Moonwalkers JOHN YOUNG (b. 1930); and GENE CERNAN (b. 1934), the last man to walk on the Moon. The astronauts swore a blue streak when their lunar module went out of control. More expletives followed in their enthusiastic descriptions of the lunar surface. When they returned, a banner awaited them: "The Flight of Apollo 10 - For Adult Audiences Only." Light general toning to mat with occasional very minor foxing; else Fine. The feelings expressed toward comedian Bill Dana are tangible - a man who was present, in spirit if not in person, on all American space flights dating back to the Mercury missions.
