Ideal commemorative cover with a cachet commemorating the launch of a Little Joe 7 booster rocket from Wallops Island on April 28, 1961, in support of Project Mercury capsule testing, signed in ink and ballpoint by the entire Mercury Seven lineup: “John H. Glenn, Jr.,” “M. Scott Carpenter,” “Walter M. Schirra, Jr.,” “Donald K. Slayton,” “Alan B. Shepard, Jr.,” “Leroy G. Cooper, Jr.,” and “Virgil I. Grissom.” In fine condition, with staple holes to upper left and erased collector’s pencil notations behind a portion of the signatures. Given the prevalence of autopen and secretarial signatures on near-complete Mercury Seven items, this neatly signed cover stands as an uncommon and highly desirable example. From the collection of aerospace memorabilia specialist Ken Havekotte. Pre-certified Zarelli Space Authentication.
