Postcard with bisected 4 cents sent to Germany - pen canc. (tied) purser S/S CANADIA and ms date 23/III 1903.
COVERS MAILED WHILE ON BOARD A GERMAN SHIP
The purser of the ship could keep a supply of stamps from the country where the ship departed, and under the
UPU rules he would post them in the first port of call where they would be accepted without penalty.
This practice is allowed today - a century later. The German steamers had their own cancels with the name of the ship - that sometimes would be
used for cancelling the stamp. On other occations the purser would use a pen and ink to write the date on the stamp. Yet another practice would be to mark the stamp with an "X" with the date written on the envelope or postcard in combination with the name
of the ship stamped closely to the date.
All German/DWI steamship postcards/covers are highly sought after. I am aware of 5 (6 also counting one lacking the bisected stamp) postcards having a bisected 4-cents stamp mailed to Germany receiving
the pen cancellation.
