Scarce flown Gemini 12 checklist used on the mission by Command Pilot James Lovell, identified on the front as "CF 55047-9, S/N 112, Remarks: Checklist," and signed and flight-certified in black ballpoint, "Gemini 12, James Lovell, Gemini 12, Flown onboard Gemini 12." The tape-bound 3.75 x 8.5 checklist contains 20 double-sided pages plus stiff covers, with tabbed sections labeled "1A/1-4," "RNTY," "Post-Retro Jett," and "Postmain." It features numerous pencil notations inside in Lovell's own hand, with a list of instructions related to drinking water written inside the front cover. Other notations record critical flight metrics such as IVI values, wind and altitude data, coordinates, and other readouts. One ink notation designates settings for the 16mm camera: "f8, 1/250, 1 Frame/Sec." The rear board bears an affixed Velcro strip for securing the checklist within the Gemini spacecraft. In very good to fine condition, with light soiling and overall wear from use.
