The card shown here, dated 16 October 1883, has a circular cancel with sanserif K K DEPESCHEN-AUFGABSAMT surrounding seriffed No V. It was sent to Friedel & Baum at Kärntnerring 17. The pencil markings are by dealers. The III in blue and 823 in a different blue are not normal pneumatic markings; however the Kärntnerring station was numbered 3 until 1892. The 823 cannot be the transmission number as that is handwritten at the bottom and is 121. This shows that KKDA-V is not Kärntnerring. [The pencilled 4-in-ring and 500 at the bottom of the back will be a society packet reference and price!]
