Postcard. Conspiratorial mail for the military Poland-Lisbon-England [1943].

1943 clandestine postage for the military Poland-Lisbon-Anglia.

Card sent from Warsaw to an "underground address" in Portugal with confirmation and thanks for parcels received, in fact through the Polish Red Cross - which acted as an intermediary in sending parcels to the country - destined for a soldier in England.

Censorship stamps, on the back stamps "POLSKI KOMITET OPIEKI / DELEGTURA w CALDAS DA RAINHA / M.O.S. W. / LISTA N.º .... N.º" with added numbers, a cylinder with very nicely documented circulation at each stage of the parcel's journey, good state of preservation.
