During the Third Reich, the premiere philatelic event of
1935 was the OSTROPA Philatelic Exhibition in Königsberg, East Prussia.
In German, OSTROPA stands for Osteuropäische Briefmarken-Ausstellung,
or East European Stamp Exhibition. The exhibition was held from June 23
until July 3, 1935.
The philatelic exhibition was held in the Königsberg Castle, which was on Steindamm Street, one of the prominent thoroughfares of the city-center. The postcards, shown above and to the left, show early 20th Century views of the castle.
Königsberg was founded by the Teutonic Knights in 1255 and was the capital of East Prussia after 1772. This Baltic port developed into a German cultural center.
The castle was begun in 1255, and then it was greatly enlarged from the 16th to 18th Centuries. It eventually became the residence of the Prussian Kings, and King Wilhelm I of Prussia was coronated there in 1861. After the fall of the German Empire and into the early part of the Third Reich, it was the Prussian Museum and was open to the public.
The Allied bombings during World War II obliterated the center of the city of Königsberg, and the castle was destroyed by a fire, as a result of the bombings.
At the end of World War II,
the city was annexed by the Soviet Union and renamed to Kaliningrad.
German residents were expelled and the city was re-populated by Soviet
citizens. Though the Soviets built a modern city there, the ruins of
the castle remained. In 1968, Soviet Premier Leonid Brezhnev ordered
the ruins demolished, as a relic of "Prussian militarism". Most of the
treasures that were in the palace museum, prior to the Soviet
occupation, have never been recovered.
The Third Reich issued the OSTROPA Souvenir Sheet shown above on June 23, 1935, the first day of the philatelic exhibition. The souvenir sheets were provided, with the purchase of an admission ticket to the exhibition, which was 1.70 Reichmarks.
The souvenir sheet is watermarked "OSTROPA / 1935" at the top and bottom. The four perforated stamps in the middle of the sheet are perforated 14, and each one is watermarked with a "cross". This is the only time, during the Third Reich, that swastika watermarked paper was not used for a postage stamp issue. The souvenir sheet is also known, with the stamps being imperforate, but it is very, very rare.
IMPORTANT NOTE. The gum used for the OSTROPA souvenir sheet contained sulfuric acid. Over time, this will cause the paper to stain a dark brown and eventually disintegrate. If the sheets are left, with original gum, it will destroy them. Collectors MUST remove the gum, in order to preserve them, and a collector should NEVER BUY ONE OF THESE WITH ORIGINAL GUM, if any of them still exist INTACT, after 75 years.
The Michel Catalog has a special note on this in their catalog. They indicate that the MINT price for the souvenir sheet is for one that is "toned a light brown color" and that is "WITHOUT GUM". The Scott Catalog has a similar notation, as well.
scanner was very kind to my OSTROPA souvenir sheet, as shown above. It
is actually a little darker than the scan indicates. I would suspect
that any OSTROPA souvenir sheets offered today that look bright and
WHITE have probably been "bleached" at one time or another.
The 3 Pf. stamp from the souvenir sheet (top-left) shows Allenstein Castle over an outline-map of East Prussia.
The 6 Pf. stamp (top-right) shows the Tannenberg Memorial over an eagle. The monument commemorates the German soldiers that died in the Battle of Tannenberg in 1914.
The 12 Pf. stamp (bottom-left) shows Königsberg Castle over an East Prussian shield.
The 25 Pf. stamp (bottom-right) shows Heilsberg Castle over what looks like a leaf.
Shown above is a cover, postmarked at the exhibition on July 2, 1935. It features the official exhibition cachet and the official exhibition "KONIGSBERG (PR) OSTROPA" postmark.
Two Ship postmarks exist for the exhibition, as well. They are the "1935 / CRANZ-ROSSITTEN SCHIFFSPOST" postmark and the "1935 / SCHIFFSPOST / GROSSES MOOSBRUCH" postmark.
