Introduction
Luxembourg's 131 face-different bridge-and-bar postmarks provide an excellent theme around which to collect stamps, postcards and covers from the first half of the 20th century. First introduced in 1905, many of the bridge-and-bar cancellers continued in use into the first six months of the WWII German occupation. By the end of 1940, most of them had been gradually replaced with the German administration's devices. A few resurfaced and saw limited use again shortly after the occupation ended in September 1944, while Luxembourg introduced new canceling devices.
During an era when most mail in Luxembourg was still hand canceled, the bridge-and-bar cancelers became the postal clerk's workhorse for canceling stamps, dating receipts, and dutifully documenting the dispatch, transit and receipt of mail. As the 35-year period of use was relatively long, examples of many of these postmarks are plentiful. For such, the challenge is to find clear strikes on postcards and covers and socked-on-the-nose strikes on loose stamps. Others, however, are uncommon, and a few very scarce, reflecting the small amount of mail handled by some of the rural post offices. Nonetheless, the uncommon postmarks still occasionally turn up in inexpensive mixtures and collections offered in auctions, on eBay and at stamp show bourses, their philatelic significance having gone unnoticed by the general collector.
A special challenge is to find bridge-and-bar postmarks on the Grand Duke Adolphe definitives. When the

bridge-and-bar cancels were being introduced, the Adolphe definitives were rapidly being replaced by the Grand Duke William IV definitives late in 1906 and Ecusson definitives in 1907. And as of January 1, 1909, the Adolphe definitives lost their postal validity. By that time about half of the bridge-and-bar cancels had been introduced. The earliest was Luxembourg-Gare-Hollerich on April 24, 1905, followed by Berdorf and Differdange the next month. Shown on the left is the two-centime Adolphe definitive canceled at Wiltz, October 8, 1905. Bridge cancels showing 1905 dates are scarce. That's why I seldom pass up an opportunity to buy an Adolphe definitive with a readable bridge-and-bar cancel!
A related challenge is to find the Hindenburg overprints with bridge-and-bar cancels. Such cancels are possible beginning October 1, 1940 (when the Hindenburgs superseded Luxembourg's pre-occupation stamps) for post offices that had not yet been issued German administration canceling devices. But by about the end of 1940, most of the bridge-and-bar cancellers had been replaced with German canceling devices, bringing their use to an end. After the war ended, Luxembourg introduced new cancellers.

Luxembourg's Federation des Societes Philateliques du Grand-Duche de Luxembourg (the "FSPL") cancel numbering system system designates the bridge-and-bar cancels (in German: die bruckenbarrenstempel) as "Type 33" in the comprehensive Catalogue des Cachets Usuels des Bureaux de Poste du Luxembourg. For a few of the face-different Type 33s, two or three varieties exist; likewise, colored inks are known for some. I have abstracted the period of use for each cancel from the FSPL catalog, although in some instances the periods may have to be expanded based on new discoveries.
Gary Little nicely categorizes the bridge-and-bar postmarks by the characters seen in the lower arc of the postmark, thus:
- Three stars (80)
- Two stars + Roman numeral (21)
- Two stars + capital letter (5)
- Two stars + "Ville" (1)
- One star + "Ville" + lower case letter (5)
- Text only (11)
-
Text + Roman numeral (7)
