This listing features a choice, specialized 8-stamp collection page charting the critical technical perforation changes of the Austrian Empire from 1861 to 1865. The lot includes early right-facing portraits of Emperor Franz Joseph I and subsequent Embossed Double Eagle Coat of Arms values.

The collection is cleanly sorted by production gauge, containing four examples of the early, fine Perforation 14 machine cuts and four examples of the later, coarser Perforation 9.5 comb cuts. A major asset of this page is the superb quality of the historical cancellations. Highlights include a bold Boskowitz provincial strike, a large Kirchberg circular cancel, a clean Wien boxed date strike, a Cili Slovenia strike, and a spectacular, fully legible Triest Adriatic port cancel. The stamps exhibit strong color preservation and excellent perforation lines. Please see the high-resolution front scan to verify the technical alignments and cancellation conditions. This complete page is sold together as a single lot.
