Six covers signed by Mercury astronauts: three multi-signed Project Mercury FDCs, each signed in ballpoint by Scott Carpenter, Wally Schirra, and Gordon Cooper; a commemorative cover honoring Wally Schirra's Mercury-Atlas 8 flight, signed in blue ballpoint by Schirra; and two Mercury-Atlas 9 launch day covers, each signed in blue felt tip by Gordon Cooper. In overall very good to fine condition, with light bands of toning and removed address labels to the multi-signed covers.
