Today we’re looking at a fresh arrival to the shop: a copy of The Astronauts: the Story of Project Mercury, America's Man-in-Space Program, by Martin Caiden. On its own, it’s an interesting account of the early space race, but a handful of illustrious signatures really cause this particular volume's value to skyrocket. We’ll explore this and other space-adjacent collectables—including science fiction and photographs from the lunar capsules—on this far-out #brattlecast.
