I'm sure you're all aware of Tom Karen - who in the late-1950s and through the 1960s was one of the UK's leading industrial designers [he was variously responsible for the Raleigh Chopper bike, the Reliant Scimitar GTE and the Bush TR130 radio].
In East Germany, he had a counterpart - Clauss Dietel - who styled a range of 'intriguing' radios and was also designer behind the "Wartburg 353" car which was used extensively by the 'Stazi" and was the East German 'Mittelklasse' transport - think of it like today's Audi A3.
See here for some interesting videos/pics of 1960s/1970s East German radio designs:
