Collection Item Summary:
Each spacecraft was equipped with removable window shades which were secured in place with hook and loop closure, and prevented the sun shining inside. Without the "safety layer" of Earth's atmosphere, the sun's light is strong and periodically required blocking (for sleeping, etc.).
This shade was used in Command Module "Columbia's" left rendezvous window during the historical Apollo 11 first lunar-landing mission. NASA transferred it to the Smithsonian in 1970.
