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.
