I can't imagine what it must have been like for Alexei Leonov to open the hatch on the Voskhod 2 and take those first tentative steps into open space. Below is a Kniga cover featuring Leonov's signature along with crewmate Pavel Belyayev. This is part of the overal Kniga collection I have.
Later, Ed White became America's first spacewalker. Below is a vintage glossy from the mission.
