1866 (7.8) Folded entire to Trieste, franked 1864 15s. brown tied superb straight-line ALEXANDRIA (first postmark of the Austrian Post Office), extremely rare late usage of this pre-stamp marking. Smith states “perhaps it served as a relief canceller when more than one clerk was required To handle peak loads”, an important showpiece, only three recorded covers; cert.
