This website is dedicated to the Hungarian born stamp dealers Béla, Géza, Eugen and Frank Szekula.
After moving to Lucerne in Switzerland each one of them opened his own stamp business with emphasis on international stamp trade.
All four brothers were probably driven by money rather than the love of stamps, and especially Béla’s creative business ideas provoked more than one philatelic scandal during his career.
However, the history of philately would arguably be considerably poorer without the Szekula family.
Eugen (Jenő) Szekula (1888–1950) was born in Szeged on March 9, 1888.
When he was old enough, he joined Géza as an employee at Béla’s Internationale Philatelisten.
On August 19, 1912, he married Elisabeth (Erzsébet) Zenner in Budapest.
Like his older brothers he then moved to Lucerne, initially still working for Béla.
In October 1913, Eugen traveled to the United States representing Béla’s company at New York’s first stamp exhibition, the New York Philatelic Exhibition.
First ads for buying stamps appeared in Swiss newspapers in 1915, and in January 1917 he opened his own Briefmarken-Import und -Export (= stamp import and export) business Eugen Szekula in Lucerne.
On July 5, 1919 he became a naturalized Swiss citizen of Geuensee.
In September 1919 Eugen closed his business at Grendelstrasse 19 and reopened it as Briefmarken-Import und -Exporthaus (= stamp import and export house) at the new address Hertensteinstrasse 56.
Like the rest of the family he changed the spelling of his name to Sekula in March 1923.
Apparently his business went well for the next ten years, but in 1933 he was facing bankruptcy.
As a result, in August of that year Eugen’s stamp import and export firm was converted into a corporation, Eugen Sekula A.G., with him as director.
In August 1934 the Eugen Sekula A.G. changed its name to Atlas Briefmarken A.G. in Luzern (Atlas Stamp Ltd. Lucerne).
In February 1935 the board of the Atlas Briefmarken A.G. in Luzern decided to leave Lucerne and move to Lugano; the corporation was renamed to Atlas Briefmarken A.G. in Lugano (Atlas Stamp Ltd. Lugano).
After less than three years, In November 1937 the Atlas Briefmarken A.G. in Lugano moved again, this time to Zurich, and became Atlas Briefmarken A.G. in Zurich (Atlas Stamp Ltd. Zurich).
The company continued to sell stamps for another thirteen years, but in the end Eugen Sekula was apparently headed for financial ruin.
On Sunday the 29th of January, 1950, the police was called to Sekula’s apartment at Rigistr. 18 where they found the lifeless bodies of Eugen Sekula (62), his wife Elisabeth (57) and their disabled daughter Maja (24).
Both parents were already dead when the police arrived; Maja was hospizalized but died one day later without regaining consciousness.
All three had taken an overdose of sedative drugs, presumably due to their desperate financial situation.
Three months later, in April 1950, the Atlas Briefmarken A.G. in Zurich was declared bankrupt.
Although he was much less of a traveler, Eugen Sekula’s business qualities probably came close to those of Béla.
A failed attempt to establish his own stamp-like labels in the Swiss postal system in 1930 shows that he was similarly creative, but he also employed the same sale tactics as Béla sending out unwanted stamp selections and then aggressively demanding payment — eventually with the same result.
In 1934 the U.S. Post imposed a short-lived embargo on both of them, even marking postal money orders as fraudulent and returning them to the sender.
Postcards — June 1912
On June 1st, 1912, the Imperial Post Office granted permission for mail transport with a zeppelin and an airplane as part of a charity event for the benefit of the Grand Ducal Center for Mother and Infant Care in Hesse. The Flight-Postcard Week on the Rhine and Main (Ressource in German), one of the first flight events with official airmail transport worldwide, was scheduled to take place from June 9th to 16th. Airmail was transported between the cities of Frankfurt a.M., Offenbach a.M., Darmstadt, Worms and Mainz. Postcards meant to travel by aircraft could be placed in any street mailbox of the participating cities during the event, but in addition to regular stamps paying the actual postage (e.g. 5 Pf for a postcard) they had to be franked with semi-official stamps issued by the organizer. Although these so-called flight stamps had no postal value, they also received a post office cancellation. On Sunday, June 9th, air post offices began selling official charity postcards and stamps. Military bands providing a respectable supporting program turned the Flight-Postcard Week into a folk festival which was publicly observed far beyond the guild of stamp collectors. On June the 10th the first airmail was transported from Frankfurt to Darmstadt by the Gelber Hund (Yellow Dog), a double-decker with yellow wings built by August Euler. Two days later, the airship Schwaben (Swabia) arrived at Frankfurt for a roundtrip with stops at Offenbach, Darmstadt und Mainz. At each stop, mail bags were dropped on parachutes and new mail was picked up with ropes and hooks while the airship stayed hovering about 50 m above the ground. Several more flights took place during the following days. Due to delays caused by technical problems and the weather leading to undelivered mail, but also to increase sales of charity postcards, the fair was extended to Sunday, the 23rd. However, delivery of the mail lasted beyond the end of the fair. The Schwaben, already back at her home base in Baden-Oos, had to return to Frankfurt, and on June 24th (according to some sources June 27th) she carried out the final flight, transporting mail that had actually been intended for the – now defective – Gelber Hund plus last-minute postcards quickly prepared by the patronage and addressed to Altes Palais Darmstadt. Unsold remainders were later sold to stamp dealers like the Senf brothers, Leipzig, and Eugen Szekula, Lucerne, who redistributed them with their own modifications. It is important to note that all these postcards were actually flown and thus qualify as airmail.
Szekula postcards can be identified by the presence of one of three different typewritten messages on the back and a hand-stamped number on the front (№ 832 … № 835).
This postcard is a complete fake created by the well-known forger Peter Winter.

Vignettes — September 1930
In 1930, Eugen Sekula had a very special idea for injecting his own creations into the philatelic market: instead of printing or writing the words “Porto bezahlt”, “Port payé” or “Porto pagato” (German, French and Italian for “Postage paid”) on envelopes meant to be sent out as cash paid printed matter, he started using stamp-like labels he had produced himself for that purpose. On September 24 the post office no. 6 of Lucerne granted permission to use these labels. After preparing a few hundred covers he began sending them out on October 10. His marketing ploy only lasted 10 days. On October 20, as soon as the postal administration of Lucerne became aware of this, further use of these labels was prohibited.
Instead of feeling defeated the businessman Sekula immediately saw an opportunity. Pointing out the rareness of his vignettes in ads placed in various philatelic journals he began selling his leftovers at high prices! Complete sets of all four stamps were offered in special glassine booklets in German, English, and French. The ones shown below contain the scarcer set of tête-bêche printed pairs.
Cash Paid Printed Matter — October 1930
Four covers and a picture postcard “franked” with Eugen Sekula’s vignettes sent out between October 11 and October 18, 1930. Due to the short period of time these labels were accepted by the Swiss post office in Lucerne, traveled covers with these labels are scarce.
