Extraordinary official vintage glossy 8 x 10 NASA photo of Mercury astronauts John Glenn, Gus Grissom, and Alan Shepard, signed in blue ballpoint, “Virgil I. Grissom,” and fountain pen, “Alan B. Shepard, Jr.,” and “J. H. Glenn, Jr.,” with Glenn signing twice. Reverse bears purple NASA caption text. Some creasing to borders (not affecting signatures or image), a tiny tear to the top edge, and some moderate contrast to portions of Glenn’s signatures against the busy background, otherwise fine condition. Shepard and Grissom made history as the first two Americans in space, entering sub-orbit on the MR-3 and MR-4 missions, while Glenn became the third with his orbital flight on MA-6. A rare, outstanding pose of the three pioneering Mercury astronauts. Pre-certified Zarelli Space Authentication.
