An exhibition of over 250 art pieces created during the communist era (1949-1990) by the deceased East German artist, Jürgen Wittdorf (1932 - 2018), has been a success. The exhibit has attracted more than 20,000 visitors since it opened last month in Biesdorf Castle, a suburb far from Berlin's historic city centre. At a time when sexual freedom is under renewed attack around the world, even amongst EU democracies like Hungary or Romania, Wittdorf's work is enjoying a renaissance four years after his death.
