On September 9, 2022, Austria, Liechtenstein and Switzerland joint efforts to release together a se-tenant souvenir sheet with three stamps dedicated to the 150th anniversary (1872-2022) of the railway connection Feldkirch – Schaan – Buchs (earlier information provided by Cesar Ittmann, the Netherlands).
Each country issued the same souvenir sheet but with perforation limited to the country’s stamp and denomination only on this stamp. In parallel, a se-tenant souvenir sheet containing the three stamps, all perforated (see illustrations below) and with the three denominations, two in CHF, one in Euros, was issued. On September 9 and 10, 2022, the train made the connection between the three places with a possibility to obtain a special cancellation from a post office installed at each station, allowing creation of triple mixed FDC covers. Stamps feature three locomotives from different eras used in each of the nations: a 1927 steam engine for Austria, an electric ÖBB traction unit from 2004 for Liechtenstein and SBB’s legendary Re 4/4 II built between 1964 and 1985.
Don Birschel (USA) submitted an interesting item looking like a se-tenant souvenir sheet containing a pair of stamps from Germany and Liechtenstein. The design of these stamps are similar to stamps issued by Germany and Liechtenstein, respectively on March 12, 2009 and March 2, 2009. Germany issued two additional stamps with similar design on May 7, 2009.
However, this item exists only with oblique bars-canceled denominations. In the margins, there are references to the Federation of German Philatelists (Bund Deutscher Philatelisten e.V.) and it is specified that the illustrations correspond to competition designs (Konkurrenzentwürfe), i.e. not-issued designs to the above mentionned stamps dedicated to the Post of both countries. In fact, each year the Federation of German Philatelists is issuing a facsimile of stamps to be distributed to their members and in 2009, they represented exceptionally stamp designs from two countries. The stamps from this item cannot be used for mail and therefore this souvenir sheet is simply a cinderella, not to be considered as a joint issue. Nevertheless, an interesting item that can be found on the web for about 4 to 5 €uros.
