Hardcover photo album with the title “Mein Leben 1921-1939”, the photographs appear to trace the life / childhood of a man by the name of Hans Krost (his name is written on the cover). It contains 70 old photos from the 1920’s and 30’s and 15 modern photos (which appear to be from the 1990’s). 3 of the photos feature Krost and a friend or family member wearing RAD uniforms, 1 or 2 photos feature kids wearing HJ uniforms. The album contains many captions that indicate, among other things, that Krost grew up in the cities of Mainz and Saarbrücken. Several photos of the buildings he lived in or the area he grew up in, both old and new photographs.
