Five-color, four-territory, two-issue, registered 42 Rpf. cover incoming to Mondorf-les-Bains in 1941

Sometimes a cover is so visually compelling as to be irresistible, depending of course on your sense of philatelic beauty.  For me, this stunner was such a cover:

Post-WWII Fiscal Use of the G.D. Charlotte 3rd Series definitives

Gouvernement grand-ducal
Office des Licences

10-Fr Charlotte (3rd Ser.) License fee for a license to import 100 tons of sugar syrup from Cuba (Contract value = US $31,500) 20 November 1946

As reconstruction began after World War II in Luxembourg, printing new revenue stamps was a low priority.  Instead, the G.D. Charlotte 3rd Series definitives, issued in 1944 and 1946, were used.  Thus, we often find these stamps with government-agency fiscal cancels, such as you see here, particularly the higher denominations.  But uses on documents are scarce.     1 1/4-Fr (4) Administration Communale Steinfort

Free Domestic Official Mail from Arsdorf in 1881

Written at Arsdorf by the Mayor,
3 March 1881

Redange, 5 Mar 1881, to

Diekirch, 6 Mar 1881

Use of Arsdorf’s Postes Relais No. 1 cancel does not appear until 1882. The FSPL Handbook lists 4 January 1882 as the earliest known use. This is consistent with this official folded letter having been posted at Redange although written at Arsdorf.
