On December 4, 2007, Luxembourg Post released the second series of special postage stamps illustrated four pipe organs of the country. The issues are composed of 4 postage stamps with different face value plus extra addition value. The four pipe organs depicted are instrument placed in Niederwiltz, Sandweiler, Echternach, and Esch-sur-Alzette .
The church of Niederwiltz owns the very first Eisenbarth-organ built for Luxembourg, consecrated in 1997. A three-manual instrument of 39 stops, built on the lines of a synthesis between French symphonic-romantic as well as French classical style, incorporating a light reference to Spain and selective connotations of southern-German baroque sound ideals.
