The Kulturplast is a relic of the GDR era. As a sort of decoration, a beautiful mosaic has been affixed to the outside, featuring the most ridiculous slogans the SED crooks could come up with.

If you’re not laughing now, you don’t speak German. Here are some linguistic gems to enjoy, such as:
The liberation of the working class can only be the work of the working class
life is our programme
and the best one:
We are the victors of history
Sure. Luckily, not this time.
