29 July 1918: Lemberg-Krakow-Vienna-Graz (a rare routing!). Flown to Vienna, forwarded by pneumatic post to Südbahnhof (chiffre 76) and onwards by train. It's overfranked: it needed only 2 flight segments at 1.50kr, handling fee of 1kr, - total 4kr in air mail stamps plus the surface letter rate of 15h. The 2.50kr is on standard grey paper, the 1.50kr and 4kr are on cream paper.
