This is putatively the last QSL card issued by Radio Berlin International. Instead of being the actual last QSL card, I think it is the last QSL card printed for RBI because I understand their final broadcast was on 2 October 1990.

I got this from someone on E-Bay. The DXer who received this QSL card was Manfred Lepp. Does anyone remember him? In any event, this is an interesting piece of radio history.
