Here's a couple of short videos focusing on West Germany, that Cold War pop-up country established in 1949 and then absorbed back into a reunified Germany in 1990. This first US newsreel records the white heat of West Germany's postwar rebuilding, including the fabulous international exhibition of modern architecture, Interbau.
And here's a smashing mini-documentary about photographer Jupp Darchinger, who captured everyday life and the political elite in Bonn during this period. His photographs are incredible, and more can be seen here.
