Highly desirable embroidered Apollo 1 mission patch deriving from the personal collection of original Mercury astronaut Deke Slayton. The patch measures 3.5″ in diameter and includes a signed letter of provenance from Bobbie Slayton dated July 23, 2005, in full: "This is to certify that this Apollo 1 crew patch belonged to my husband, Deke Slayton, and was given to him by Gus Grissom. It was locked in his safe deposit box along with other space memorabilia. This patch was is genuine in all respects." In fine condition. From one Mercury astronaut to another, this is a highly coveted original Apollo 1 mission patch—examples of such were only distributed to the crew and a few NASA workers.
