The collection reprints identical images and descriptions from Kampf um den Weltraum, published in 1967 by Heinerle-Hugo Hein.

Card #195 features an Apollo 11 lunar landing mission crew photo from May 1969: Commander Neil Armstrong, Command Module Pilot Michael Collins, and Lunar Module Pilot Edwin "Buzz" Aldrin.
