Unusual Manned Spacecraft Center "Travel Memorandum Worksheet" for expense reimbursement, filled out and signed by Grissom, "Gus," one page, 8 x 10.5, no date but circa September 1966. Grissom fills out the dates, times, and modes of transportation for travels between Houston, Cocoa Beach, and Orlando from September 17th to 23rd, noting the $69.20 cost of an airline ticket. Below, Grissom writes an explanation of the charges, in part: "Rental car use 10 mi personal use…I paid for my airline ticket because I couldn't find my TR's. Enclosed is the ticket receipt and the American Express receipt for the ticket. It will be a week or so before I get the rental car receipt." In very fine condition. Accompanied by a full letter of authenticity from Zarelli Space Authentication. A unique piece of Apollo program history, evidently documenting Grissom's journeys between the Manned Spacecraft Center at Houston and the Kennedy Space Center near Cocoa Beach.
