~ Glück auf ~
Glück auf! literally means "luck up" or "good luck coming back up" which all miners look forward to. Note the miner king with his orb as a bomb and lighting stick, the hard working miner and the gnomes working in the mine. This could be considered a miner's occupational. It is a Mettlach PUG (printed under glaze) stein mold number 1909 and decor number 980 made in 1896.
Glück auf!
Verkündet es mit lautem Schal!
Glück auf ihr Knappen all.
Good luck!
Proclaim it with a loud bomb!
Good luck to all you miners.
