A mint block of 15 of Luxembourg #7 [10c imperforate]. This half sheet includes the only Luxembourg tête-bêche pair ever issued. (Only one other pair of #7, part of a full sheet of 30, is known to exist.) This sheet had a reserve of DEM 8,000 at the Jakubek auction of
October 12, 1987 in Hamburg, but did not sell.
Luxembourg #B242a [children's painting with 2F+25c denomination missing]. This rare "missing value" error comes from the 1964 Caritas set featuring children's paintings of Luxembourg City landmarks. It seems that only one pane of 100 escaped the post office, distributed as four sheetlets of 25. However, there are only about 10 documented single copies known. From the Hamilton collection.
Rare Covers
Here are some rare classic covers of Luxembourg to admire:
A strip of 5 and a pair of Luxembourg #1 (1856). The fourth stamp of the strip shows the plate variety "line through upper left ornament". This is the earliest known use of this variety on cover. Sold for CHF 19,000 in Christie's auction of May 28, 1991 in Zürich.
A block of 4 of Luxembourg #1 (1855). The stamps are cancelled with two 3-ring cancellations and there is a Belgian-style Redange sidemark. Sold for BEF 34,000 in the Willy Balasse s.a. auction of June 22, 1996 in Brussels.
A strip of 4 of Luxembourg #1 (1856). The cancellation is the 9 bars of Luxembourg and there is a large framed "P.D." marking. Offered in the Willy Balasse s.a. auction of October 25, 1997 in Brussels. The estimate was BEF 20,000-30,000.
14(!) of Luxembourg #2. Sold for CHF 75,000 in the Corinphila auction of October 26, 1982 in Zürich, the highest price ever paid for a philatelic item from Luxembourg.
Luxembourg #7 [10c blue, imperforate] (12-June-1866). The stamp is a top margin variety and bears a 3-circle cancellation. There is also a rare 2-circle French-style Weiswampach side mark. This cover was offered in the Soluphil auction of January 29, 1997. The starting bid was FF 3,000.
Luxembourg #62a [20c brown error] (1905). This cover is the one of two known that is postmarked in Grevenmacher (the usual postmarks seen are Wasserbillig and Wecker). It was sent to Vienna.

Charity Seals
Marie-Adélaïde Caritas forerunners (1908). This beautiful cover hosts a complete set of the 1908 Marie-Adélaïde Caritas forerunners and is postmarked June 15, 1908 (second day of use!). These charity seals were supposed to be affixed to the back of an envelope, but the postmaster in Diekirch obviously looked the other way in this case. From the Little collection.
Anti-Tuberculosis charity seals (1950). This first day cover features all three color varieties of the charity seals issued in booklets on March 21, 1950 by the Ligue Luxembourgeoise Contre la Tuberculose. From the Little collection.
German Occupation
Hitler Siegt! cachet. This 1941 cover has many desirable attributes: a Hitler Siegt! (Hitler Wins!) "V" propaganda cachet (in red); an Adolphe Bridge pictorial cancellation; and a "Drucksache." rubber stamp marking. In addition, the envelope has an embossed Luxembourg coat-of-arms in the top-left corner and is from "Der Oberbürgermeister der Stadt Luxemburg" -- the mayor of Luxembourg City. From the Little collection.
Sowjet-Paradies cachet. This unfranked cover from the office of the Mayor of Luxembourg to the Worker's Board has a violet Sowjet-Paradies propaganda cachet. This cachet was used to promote an exhibition deriding life in the Soviet Union. The cover also has a circular "Stadt Luxemburg" rubber stamp and a straight-line "Abt. Familienunterhalt" rubber stamp. From the Little collection.
Liliput cancellation. This special cancellation was used to promote the appearance of Schaefers Märchenstadt Liliput -- Schaefer's Fairy City of Dwarfs -- at the Schueberfouer fair in 1941. This was a traveling exhibit of a real city of dwarfs, complete with its own post office. From the Little collection.
