1833, "STADTPOST / QUITTUNG / FÜR / BERLIN    SILBERGROSCHEN", embossed white label in irregular block of 4, accompanied by a dated lettersheet with date stamp "BERLIN 8 5", showing on reverse large red wax seal of the Prussian 'Hofpostamt', and addressed to the Imperial Austrian first postal administrator Maximilian von Ottenfeld. These stamps have been a mystery since their discovery in the 1960s. Most likely these are specimen for a new design of the Berlin city post receipt labels which had been issued in the 1820s and had been send on demand of the Austrian Postal authorities to Vienna. To-date no further copies have been recorded.
