Deke Slayton's embroidered Apollo-Soyuz Test Project mission patch attested to as being flown aboard the Apollo CSM-111 for nine days in space, 4″ in diameter, fully embroidered with a merrowed edge and ‘tail.’ In fine condition. Accompanied by a certificate of authenticity signed by his wife, Bobbie Slayton, which reads in part: "This is to certify that this Apollo Soyuz crew patch belonged to my husband, Deke Slayton, and was flown on that mission in 1975. It was locked in his safe deposit box along with other flown memorabilia."
