In 2018, the Stamp Day will be held in Kayl-Tétange and is hosted by the local philatelic club. Käl and Téiteng (in Luxemburgish) are located in the south of Luxembourg, also known as “the land of the red rocks”, due to its characteristic vast iron ore deposits. Alongside the raw materials extraction, a whole new industry sprung up which also included the design and manufacture of technical devices. With the issue of this special stamp for the Stamp Day 2018, POST Philately is introducing a new series. The host association can choose the motif; it just needs to be closely related to their home municipality or region.
