Fantastic original 1959 NASA newsletter detailing progress on the Mercury program, 4 pages, 8 x 10.5, vertically signed in ballpoint on the front page by all seven original Mercury astronauts, each on his respective photo: Malcolm S. Carpenter, Leroy G. Cooper, John H. Glenn, Jr., Virgil I. Grissom, Walter Schirra, Alan B. Shepard, Jr., and D. K. Slayton. Moderate contrast to a few signatures and faint, unobtrusive vertical fold, otherwise fine, crisp condition. The combination of this scarce and very desirable grouping (with the signers’ less-common “formal” signatures) on an early item with a direct association to the Mercury program makes for an exceptional treasure that deserves a place of high honor in any space collection!
