Three official semi-glossy 8 x 10 NASA contact sheets, each featuring 12 different images of the Apollo 17 lunar module backup crew at the Kennedy Space Center. Two contact sheets show backup CDR John Young and backup LMP Charlie Duke entirely geared up for outside EVA testing, and the other shows the crew undergoing EVA tests inside KSC. Reverse of each contact sheet bears faded NASA caption text. In overall fine condition, with scattered light silvering. From the collection of Dan Schaiewitz, who worked as Extravehicular Crew Training Engineer at KSC.
