June 1934: Incoming air mail was treated in a similar fashion to outgoing: this example carries WIEN FLUGPOST, TELEGRAPHENAMT WIEN, & WIEN 1/1 15. This is the Kärntnerring pneumatic office, and the letter is stamped there at 19:39pm on the 16th June 1934 and also 8am on the 17th: perhaps they realised there was no point in sending a messenger out as the Wagon-Lits office would have closed for the night?
