Charles Conrad’s flown Skylab 2 ‘CKW’ initialed crew patch carried into space during the first manned Skylab mission, 4″ in diameter, affixed to a letter of authenticity signed “Charles Conrad, Jr., Skylab I CDR.,” which reads: “This cloth patch is one/two similar designs of the Skylab I emblem that I have in my personal collection. The above patch has 'CKW' to the right of the Skylab space station, which are the initials from our last names…This patch was carried with us during the launch of the SL-2 vehicle on May 25, 1973, and flew in space for 28 days. My crew and I made repairs during that time to enable a full duration mission. We returned to earth on June 22, 1973.” Attractively matted and framed with an embroidered "U.S. Navy" patch—representing the naval service of all three Skylab 2 crewmen—to an overall size of 10.25 x 16.25. In very fine condition.
