If you lived in east Berlin during the 1950's, ten years after the end of WWII, Germany would be rebuilding. Cities like Berlin, which had been severely damaged during the war were emerging from the rubble as the 'Wirtschaftswunder' or 'economic miracle' transformed West Germany.
In the immediate post-war period hundreds of thousands of allied troops were stationed in the divided country, many of them with cameras.
