In 2009 the Luxembourg post issued a fourth set of stamps in a series featuring pipe organs located in this small European nation. This set of four is much like the first three in many respects. Whereas the third set had blank selvage (paper bordering the stamp image) this set returns to using paper with musical notation on the selvage, as was the case with the first two sets.
The low-value in this set features the organ in the Philharmonie Hall, a Karl Schucke instrument completed in 2005. It is a massive instrument of four manuals and pedal, including a 32' stop in the Hauptwerk division. In addition to the stoplist, the hall has provided a few publicity shots of the instrument here.
