It's a declared value letter, sent from Warszawa to
Monsieur le Baron D'Autencourt
Mareshal de camp de l'armee francaise affiches
de la legion d'honeur, Chevalier de la croise
Militaire de Pologne...
It bears the Warszawa 30 october and the Strzalkowo 1 november linear postmarks plus the other additional postmarks CHARGE for the declared value, TP/PP for the pre paid letter and the transit postmark entering in France. Why PAYS BAS (PAR GIVET) instead of PRUSSE?
But the most interesting part of this letter is on the back...
The letter arrived the 13 november 1820 (pittoresque arrival postmark). The sender of this letter applied just the central seal, while for charged letters it was required that all the opened sides was closed (usually with 5 seals). So, the post office clerk added the missing four and on the side seals you can see the shape of the STARAWIES postmark.
Polish wax seals are not so common, and Starawies in particular is not listed in the books i have, even if the shape matches with the ones of the other post offices. Must be rare...
Could i just understand something more...
The lac is not so readable...
In the middle you can see the shape of the Real Krone
Below, the STARAWIES word, and the post horn symbol.
Along the side, the words "KON.PP.POST.WART.AMT"
