~ Morgens, mittags, abends, nachts ~
The stein is from the Jugendstil (youth style; modern art) period of the early 1900's and was made by Merkelbach & Wick.
Morgens, mittags, abends, nachts
trink dein Bier und sonst verachts
At morning, noon, evening, night
drink your beer and maintain self-respect


The same verse is found below on a 1/2 L. Mettlach PUG (printed under glaze) stein #1909 (decor #942) with a whimsical scene of a rooster awakening a watchman whose apparently been drinking beer from a stein all night.
