Heinrich Köhler 384 Auction – Day 1 Single Lots: Europe and Colonies, Kingdom of Lombardy–Venetia – The "P.G." Collection

1885 (September 18), 5pa black on olive, perforated 13.5, overprint Type I, tied to local postal card by Poste Slivno c.d.s. in blue, a most unusual and scarce usage of the 1881 5pa value overprinted, fine; with 2022 Hitzler certificate noting the franking as “extremely rare.”
Note: the 1880/1 5pa was no longer available at the Post Office at the time the 1885 Provisional Lion overprints were prepared. However, individuals and commercial firms could continue to bring their stamps to the Post Office to be overprinted.  Usages of the 1880/1 5pa overprinted issues are correspondingly rare.
