The card, dated 16 October 1883, has a circular cancel with sanserif K K DEPESCHEN-AUFGABSAMT surrounding seriffed No IV. The red stroke will be the Instradirungschiffre for Telegraph Central Station, and the address of Neutorgasse 17 is in the next-but-one street. The card is creased, ie has been folded for transmiaaion. Assuming sensible handling, this proves that KKDA-IV is not the Telegraph Central Station.
