And in childhood, I have never forgotten these dates - the days of the press, artillery, miner, aviation, radio. Still: in the kitchen there was a tear -off calendar, I studied with all the thoroughness that I was capable of. On the day of the radio, the calendar page was decorated with a portrait of a noble and bearded old -regime uncle.
